* '''Downplayed''': Bob is kind of a jerk, but Alice stays with him.
* '''Justified''':
** Bob really does have a very deeply HiddenHeartOfGold, and Alice is trying to bring that out of him.
** Alice has incredibly poor self-esteem and thinks she can't do any better.
** One or both grew up in a household where their parents were going through a similar situation, so they think it's normal.
** Alice's parents [[ArrangedMarriage arranged]] the matched and brainwashed her into overlooking all of Bob's faults no matter how severe.

* '''Parodied''': Bob threatens Alice with a switchblade, beats her silly, and drinks until he blacks out, but she just ignores it for the sake of love...[[MinorFlawMajorBreakup until he leaves the toilet seat up]]!

* '''Enforced''':
** "Like, [=OMG=]! This fanfic about Bob and Alice is gonna be soooo good! I'll just have her say that she loves him when she gets beaten!"
** "We need to show that Alice's love for Bob is true, no matter what may come between them! Let's have Bob do things that'd test anyone's patience and see how Alice diffuses them."
* '''Lampshaded''':
** "Let me guess, you love him, right? That's why you keep letting him do that?"
