Two Christmas' ago we had an intervention with my female cousin who was being beaten by her boyfriend and her boyfriend for beating her, at first they both tried to act like it wasn't happening but then my cousin just broke down crying and admitted he had been beating her. The boyfriend still tried to deny it at first but then admitted it too, my cousin went into a bedroom with my sisters and the boyfriend was in the living room with me and my brother, we told him how it was wrong, that no woman deserves to be beaten and how would he feel if it was his mom or sister. My sisters said they told my sister how she has kids and doesnt need to grow up seeing her in relationships like that and she could move in with them if she needed someplace to stay. The boyfriend was putting up a front like he was listening and agreeing with us saying he was wrong and would change but we knew he was lying, my sister told my cousin that if things hadn't changed by March then leave the guy and move in with her, she said ok. They came back over on New Years acting like they were so in love, we again talked to them about abuse and my sister told her her March offer still stood, On March 1st our cousin sent a copy of a marriage certificate to our group chat and said if we couldn't be happy for her AND HER HUSBAND then she didn't want to see us anymore, we didn't see her or her kids for a about a year, she had cut off all communication, moved and we didn't even know where they lived. The guy beat her up in front of one of his friends and they called the police, police came beat his ass for resisting arrest and she called my sister, after this she still went back to him, she had moved in with my sister and was sneaking to see him. We think she had planned on leaving her kids for my sister to take care of and she was going to be with the guy because she came up with some story that her job was to far away to drive back and forth so she was going to stay with a friend during the week, her kids would stay with my sister and she'd see them on the weekends. She did this for 3 weeks until my sister called her out about it telling her she knows she's still seeing the guy. Their relationship only ended when the guy dumped her for another woman
