My partners ex and I had a very functional relationship up until six months ago, We primarily dealt with each other as my partner and her have issues communicating nicely with each other. We share 50-50 custody with his ex and her partner. An issue came up where she felt I had undermined her and tried to make her look bad, which wasn't the case, it was a miscommunication between my stepdaughter and her mother. I don't know if my stepdaughter does this on purpose because she doesn't like it when her mother and I communicate as we both know then what is going on with her and in her life, Or if she Genuinely misunderstand things I say I miss communicates it to her mother. This has happened lots of times where my stepdaughter has taken what I've said and not relayed everything said or has not told the whole truth about what was said and her mum has flipped out. She will get straight on the phone and abuse my partner about what I apparently said without asking what was said nor giving the benefit of the doubt. Even once explained what the miscommunication was she still did not believe me and now we haven't been talking since September last year. She is now doing everything in her power to push me away from her children. Even to the point of listing demands upon my partner that I follow, which restricts me from doing certain things with the kids, which has thrown our routine into disarray as my partner feels it necessary to follow through on such demands to keep her happy. One of my big issues at the moment is: She has requested that i don't talk to the other mothers at school as they are her friends and she thinks its weird. I say that she didnt have a problem before our argument, in fact she encouraged me to befriend these mothers. I also think that it is important for me to have a friendship with the other mothers, especially for the kids, they like to have friends over and its important that i can speak to them without feeling that she will find out and make a big deal about it. It has gotten to the point where some of the mothers have made comments that I am being standoffish and weird and they want to know what's going on. I don't mean to be, but i feel so uncomfortable talking to them now because I'm worried about upsetting her. So after trying to take her feelings into account and only saying the basics to the other mothers like Hi, bye and giving a quick smile, and not engaging in big discussions, she then got on the phone to my partner and wanted to know what my problem was and why I was being rude to people at school. This woman is driving me crazy and I don't know how much more I can take from her. Does anyone have any tips or advice?????
