So my Sister In Law has been in a relationship for about two years now with her fiancé and I can see he is very jealous and controlling and to me I believe he is abusive. I’ve voiced my opinions to her and she keeps saying they’re in love and they’re happy. We all currently live together and I constantly hear them arguing and her crying. Her fiancé recently got so mad during an argument of theirs that he punched the fridge and broke his hand. I’ve watched him yank her out of her car before while she was blackout drunk and she nearly landed on her face. He told her he gets jealous when other people make her happy even if it’s family and that he wants to be the only one that makes her happy. He alienated her from family and friends and she feels guilty whenever she does go out because she knows he’s not happy about it. She constantly makes excuses for his behavior and it’s so frustrating. Her brother and I are the only two that try to talk to her and show her this isn’t healthy but I feel like we get nowhere and I don’t know what to do anymore. They’re about to close on a house of their own and get married in a couple months. I fear that when it’s just the two of them with no one else around to witness or hear what’s going on that things will escalate. What should I do? I feel like I’ve done all I can do. I’ve talked to the rest of her family and they all “support” her and say, “well, she loves him so I guess we have to love him.” To me that is not support. I just want to know that I’m doing the right thing by voicing my concerns to her.
