In brief, an ex and I were together for eight years, and we split up five years ago. It was painful at first but we worked through the difficult times to become close and supportive friends. He's now married, with a baby. I'm really pleased for him - he always wanted to settle down. He's a brilliant devoted dad and it's lovely to see. The difficulty is that his wife has always felt so incredibly threatened by our friendship, and has put all sorts of conditions on it. She has barely ever even managed to be polite to me, she uninvited me from their wedding, she has stipulated that we are only "allowed" to see each other once a month (if that), and on the few occasions when I have visited their house she has never made me welcome (eating separately from us, making snide comments, turning the TV on loudly when we were talking, etc). I often end up feeling really upset after these visits - but the friendship matters to me and I guess it's worth sometimes feeling crap for.
Am I being unreasonable to hope that she would be able to trust him enough to see our friendship as just a friendship, nothing threatening, not something that she has to try to control or destroy? AIBU to hope that she would try to be friendly to me out of kindness to him? I realise that she feels jealous and insecure, but AIBU to think that she doesn't have to act out her feelings like a spoilt toddler?
