So about 3 months ago I was dating a separated guy but his ex wife put me through hell because she was jealous. Then one day she even bashed me up with her new boyfriends mum, so then we had court and my lawyer didn't even show up so we decided to drop charges between us and leave what happened. Now suddenly she wants to be like a best buddy coming to my house etc etc, but I do find it hard to trust her and how to explain that to her, any suggestions please?
