My FMIL is very manipulative and unpredictable. She will buy my fiance and I dinner but then expect us to be at her beck and call because of it. She buys things for us we never asked for, but we thank her and accept because she insists. It's to the point where I don't want anything from her because she will try to use it as leverage for something. Recently, she did something on my birthday that, given her history, I wasn't sure was manipulative or just in poor taste, so I asked my fiance about it. He got upset and mentioned it to her. He asked her to think about how she behaves around his future wife. Ugh! I know! We had a talk about things that should stay between us. I was just asking for his opinion!
Anyway, she immediately flipped out calling us both rude and ungrateful, sending a barrage of accusations and hate, and listing all of the things she has purchased for us (things we never asked for nor felt comfortable telling her "no" when presented with them). She said that she wasn't going to watch what she says around me, berated me for telling her "Thank you for the birthday gift" instead of "Thank you for the [specific item]," on my birthday, and then said she is only going to see us at holidays and only going to say "Hello" and "Goodbye" to me. She said she thought that I was "manipulative in telling him about the thing she did because I knew he would tell her." She then told all of his sisters about how terrible she thinks I am. I waited a long time to respond. Finally, I decided to apologize for the birthday gift thing (since it seemed to upset her), but I also stood up for myself and said that I did not believe that I had been constantly rude or manipulative. I ended the message saying that I hoped we could all move past this. She responded with more berating messages, so I didn't answer again.
Since we paid for the wedding ourselves, I did not put her on my list of who can enter/use the bridal suite. She hasn't spoken to us in weeks after she berated us. Does she think she'll be welcome there?! She'll have access to the family area of the venue if she likes, but I do not want people in the bridal suite with me who are behaving like that. I worry about her reaction. Do you think I am doing the right thing? It will probably make things worse if I do it...
