Someone in my family is the worst about this:
Her husband leaves her while she's pregnant
She takes him back
Her husband sleeps with men while they are married
She takes him back
He breaks their 6 week old daughters arms
She takes him back
She has another child with him
She takes him back
He leaves her once he came out of the closet, if it weren't for that she'd still be with him while he sleeps with random men with no condoms
She takes him back
She lets him sleep on the couch while her new boyfriend sleeps in her bed because he can't support himself
She takes him back
She gets married to the new boyfriend, who is VERY mean to the child that had her arms broken by her previous husband
She takes him back
She has another child, with the new man
She takes him back
He takes her purse away from her in an argument while they are fighting so she can't leave the house to cool down, she hits him to get her car keys, he calls the cops and gets a battery charge against her
She takes him back
He leaves her while she's in the hospital recovering from a c-section
She takes him back
She finds out she is pregnant again
She takes him back
Finally gets her tubes tied
She takes him back
She finds out he's been fucking HER mom for 8 years, her Dad watched them fuck
She takes him back
The husband sets her up with her ex-husbands brother, so he can say she also fucked someone else in the family
She takes him back
He gets very jealous and starts demanding to know where she is, when said ex-brother in law moves to the area
She takes him back
She wants to leave him, but keeps him around (all the while going to marital counseling for years every single week)
She takes him back
Just last week- we find out he's been sexually molesting the 13 year old (the one who was hurt at 6 weeks old)
She takes him back
Asshole lawyers up and we don't know where he is right now.
I can't even imagine who she might pick next. She's only been with these two men in her whole adult life. Her kids are going to have so many issues, more than they have because of keeping worthless men around.
