cousins bf

just a rant. my cousins boyfriend tried to get with me, so i told her and sent her screenshots. now she’s mad at me??? and taking it out on me? I’ve done nothing wrong and in the screenshots she can see me telling him to stop. I’m married and she knows I would never try to get with her boyfriend. I just don’t understand why she’s treating me like the bad guy when he’s cheated on her multiple times and lies to her all the time and tells her to kill herself. I literally did nothing wrong except tell her I guess because that’s the way she’s acting. he texted me and threatened to tell my husband im cheating on him (not true) just because i exposes him to her, i could’ve really did him dirty and blasted it every where. But i tried to do this the nicest way possible. she broke up with him, but they should’ve been broken up because he told her he cheated a couple weeks ago when she was out of town. she said “he’s changing” no. also may i add he’s 24 and she’s 17.
