Apologies. Don't get me wrong, a heartfelt apology is a very good thing. But in situations of ab**e, a seemingly heartfelt apology can be part of the ab**e cycle.

They'll apologize, buy you gifts, etc until they get you back, then it's right back to negative behavior. People who ab**e their spouse will apologize so sweetly that you'd think they'd never hurt anyone again, until they do.
