Visitation Problems with fiance

Guest

Hi im just writing to ask for general advice. I have a fiance now for 1 year. He has a child and his ex has custody. He pays child support and when they went to court was awarded supervised visitation. the judge chose to make the person supervising the visitations the babys mother, so now my fiance has to go see his son at her house, alone. At first this bothered me and it still bothers me but i can live with it. its only twice a week.

What bothers me is that his ex doesnt even know me and is always saying how she doesnt want me around their child, and it makes me feel bad. When i accepted the arrangedment it was with the hope that one day she would at least want to meet me and maybe we could even get along since me and my fiance are getting married soon. I think it would be better for the child and everyone if we all got along but she wants none of it. The big problem though is they recently had a birthday party and my fiance didnt even invite me. It was at her house and i understand that its her house and if she doesnt want me there there's really nothing he can do, but I feel really left out and hurt that he wont even try to ask if i could go. He just does what she says cause she'll get mad and say that if he doesnt do whatever she says that shell go to court and have his rights terminated. Im worried about when the baby is bigger and he wants to go out to the park or something. I wont be able to go and it will be just my fiance and his son and his ex. Its like theyre still together. Should i Just walk away from this mess? Butt out? Or should i ask my boyfriend to go back to court and see if he cant have his visitations somewhere else like maybe one of the grandmothers house? I feel really weird and i want this resolved before i decide to marry him. Does anyone have any suggestions? would you all accept such a crazy arrangement?

P.S. His ex doesnt even want me calling him when hes over there with the baby because she says its interrupting ect. and the babys only like a year and a half so he doesnt know yet.

please help....
