How do I help my sister out of an abusive relationship? Recently I found out that my sister’s boyfriend has been abusing her. It started to get worrying when he would isolate her and refuse to let her get a job. She still doesn’t want to admit what he’s doing and it concerns me that she’s staying with him. They have a daughter together who’s 2 and she’s terrified of her own father. I don’t know exactly how to help her out without him flipping out and doing something to them. I wanna help before it gets worse.
