Notable that Triple H and Stephanie went through their entire on-screen relationship from start to finish before they began to date in real life. In one DVD interview, Triple H half-jokingly says that one reason for their happy marriage is that they got to do a dry run before the real thing.
Randy Savage and Miss Elizabeth are one of the most famous classic WWF examples, though they are also a subversion as they were married in 1984 before they worked together in WWF where they were presented as a couple. Their in-character in-ring wedding took place at Summerslam 1991. They divorced in 1992.
(In)Famously, Chris Benoit and his wife, Nancy. They fell in love during an angle where they were having an affair behind the back of her then-husband, Kevin Sullivan - an angle Sullivan pitched.
Kayfabe being what it was back then, this angle involved Chris and Nancy being seen at the same clubs, eating at the same restaurants, and even staying in the same hotel rooms, appearing to all the world as though they were the genuine article. The fact that they hooked up for real probably made Kevin Sullivan the only wrestler to ever be duped by his own angle. And given the... unpleasantness of a few years back, not a few conspiracy theorists armed with very-coincidental-but-still-interesting evidence have suggested that Sullivan may have been involved in the incident and staged it to look like a murder-suicide on Benoit's part. Booking his cheating wife and the man who stole her out of the picture, as it were.
Eddie Guerrero was married to Vickie Guerrero until his tragic death in 2005. Vickie only became a significant on-screen character after her husband's death, developing into a hated heel manager in WWE, a character that she later played in AEW as well.
Matt Hardy was Amy "Lita" Dumas's boyfriend both on-screen and off, but she cheated on him in Real Life with Adam "Edge" Copeland (who cheated on his wife, thus breaking up his second marriage in barely five years. The first was to Sean "Val Venis" Morley's sister Alannah. WWE had intended to make an angle out of that, but it was scrapped after Val reportedly had taken too long to come back from a neck injury). You know what happened...
Matt later dated and married Reby Sky, with whom he has four children.
Brock Lesnar (who had a fiancee and baby at home) met Sable during his 2003 run on SmackDown. Today, they are married. And before that, Sable was married to Marc Mero, though they met before she got into the wrestling business.
The Undertaker married Sara in 2000, she became an on-screen character in 2001. They divorced in 2007, he later married Michelle McCool in 2010.
John Morrison and Melina (on and off). They met during auditions for the third season of WWE Tough Enough (Morrison made it; Melina didn't, but she eventually got signed anyway), and stayed together for over a decade before finally calling it quits in 2015.
Morrison later met, dated and married Kira Forster (known as Taya Valkyrie and WWE NXT's Franky Monet) who he met on AAA and Lucha Underground.
Billy Kidman and Torrie Wilson first got together in WCW after becoming a couple on-screen, then got married while they were in WWE, where they were never an on-screen couple (at their insistence). They have since divorced.
CM Punk dated Daffney Unger and later Traci Brooks during his time in Ring of Honor. Then, while in OVW, he dated Maria Kanellis, but they split up due to WWE moving them to two separate brands (there are also rumors of him having an affair with Kelly Kelly around this time). Then he briefly dated Lita. Then he started a long term relationship with Beth Phoenix, which ended by 2011. Punk also reportedly had a fling with Mickie James and in 2013 started dating A.J. Lee. They got married in 2014.
In TNA/Impact, there's Jeff Jarrett and Karen Angle, Kurt Angle's wife. After Karen's divorce from Kurt, she married Jeff (who lost his last wife, Jill, to cancer) in real life.
The Miz and Maryse got married in 2014 and have since had two daughters.
The entire two-year feud between Tommy Dreamer and Raven in 1995-1997 was fueled by the simple premise of Raven hating Dreamer going back to when they were kids and Dreamer had been mean to Beulah McGillicutty when she was the fat girl at summer camp. Beulah debuted as a Heel at ECW Hostile City Showdown in April 1995. At House Party 96, January 5, announcer Joey Styles was trying to conduct an in-ring interview with Beulah and Raven's flunkies Stevie Richards and The Blue Meanie in which Beulah announced she was "pregnant." Raven proceeded to beat up Stevie and the Meanie until Beulah said, "It's Tommy's!," thus turning herself Face. Dreamer ran in and beat up Raven, including piledriving him on a STOP sign and a blueberry pie. Dreamer and Beulah would remain a couple on-screen and off until she left in Summer 1998 after The Dudley Boys broke her neck with a Dudley Death Drop. Dreamer, real name Thomas Laughlin, and Francine (Fournier), Beulah (Trisa Hayes)'s Arch-Enemy both on-screen and off, would have a relationship offscreen until Laughlin apparently changed his mind and went back to Hayes. Reportedly, Fournier was angry enough about this that Laughlin and Hayes had to have extra security at their wedding. This was what Joey was referring to when he said that Dreamer had "scorned" Francine, following Francine's interference in the Dreamer/Sandman-Dudley Boys main event at ECW One Night Stand, June 12, 2005.
Bryan Danielson (then better known by his WWE name of Daniel Bryan) and Brie Bella got married days after Wrestlemania XXX. They have two children together.
John Cena was dating the other Bella Twin (Nikki). He proposed to her in the ring at WrestleMania 33, she accepted, but the two would split up months later.
Cena also dated Victoria for roughly a month back when they were both in developmental in 2002 while her marriage was on a break. The relationship ended when they both got to the main roster.
In his autobiographyA Lion's Tale: Around the World in Spandex, Chris Jericho claimed to have dated Kimona Wanalaya while in ECW in 1996 and two unidentified members of the Nitro Girls (a dance troupe who would entertain the crowds between matches and going into and coming out of commercial breaks on WCW Monday Nitro from 1997-1999), though none of these situations carried over into angles.
In addition to the rumored fling with Punk, she is also rumored to have had an affair with John Cena whilst she was engaged to Dykstra and while Cena was still married. Kenny Dykstra confirmed as much during the media whirlwind over Cena's divorce in 2012, though both Cena and James have openly denied it. Dykstra also alleged that the end of the relationship was responsible for both the end of his push and his eventual release, and James being switched to WWE SmackDown in 2009.
Rusev and Lana are married as well. Before the marriage, their relationship resulted in some nonsensical Real Life Writes the Plot moments in kayfabe when WWE tripped over themselves thinking they had to respond to a TMZ report that the pair had announced their engagement (as in-universe Lana had betrayed Rusev to be with Dolph Ziggler at the time, while Summer Rae had paired off with Rusev, which got completely thrown out of the window when the TMZ story hit). You can read the bafflingly messed-up story here.

In a rare subversion for a wrestler/wrestler relationship, Natalya Neidhart and husband Tyson Kidd. In spite of working together in several different promotions before making it to the WWE together, wrestling ultimately wasn't the impetus for Nattie and TJ's relationship; they had known each other since childhood, and were together for well over a decade before they finally got married.
The nude photo scandal in February 2015 revealed that Seth Rollins was having an affair with NXT Diva Zahra Schreiber — while both were reportedly engaged (Seth's then-fiancee, and girlfriend of six years, was in fact partially responsible for said scandal). The only reason he wasn't punished was because of Triple H, though his new girlfriend did eventually get the shaft six months later, ironically for something that had occurred before she had even met Rollins. They continued dating afterwards for a bit before breaking up in February 2016 to little fanfare.
In May 2019, Rollins and Becky Lynch publicly confirmed they were dating (they had actually begun doing so shortly after the 2019 Royal Rumble — coincidentally, both won their respective matches), and they got engaged that August. A year later the couple had a daughter, and they got married in 2021.
Matt Cardona and Tenille Dashwood/Emma were together for about a year. Cardona is now married to Chelsea Green/Laurel Van Ness, and Dashwood is engaged to Riddick/Madcap Moss.
Paige/Saraya had (short) relationships with numerous wrestlers on the roster while she was still down at FCW/WWE NXT, including Xavier Woods, Dean Ambrose, (possibly) Seth Rollins (which meant that Zahra Schreiber wasn't the first person he cheated on his fiancee with), and Brad Maddox (who would release some of Paige's sex tapes in mid-2017). Most infamously, she started dating Alberto Del Rio at the start of 2016, to great controversy. Del Rio was in the middle of a divorce and allegedly had a fling with Charlotte Flair just a short while ago, but those weren't what disturbed everyone. It was the age difference between the two, and how the relationship coincided with changes in Paige's behavior, including getting two tattoos of the guy literally months into their relationship, two wellness policy violations one after the other, and Paige deciding to propose to him not even a year into their relationship in another company's wrestling ring. The two continued to generate controversy for the next year (including the aforementioned sex tape scandal and a recording that caused an investigation into possible domestic abuse) before breaking off the engagement in October 2017.
