Check out today’s We Family Wednesday

My fiancé and I have been together for 11 years, 2 years ago we found out that he has a 12 year old child. We have 3 children together & from day 1 we let it be known that we were going to handle this as a family. Not my idea but my fiancé thought it would be a good idea for me to reach out to the child’s mother when it was confirmed he was the father and just let her know that he did want a relationship with the child and where we should go from there as far as what would make the child more comfortable when meeting him. Right away the child’s mother made it clear that she didn’t want to talk to me, she wanted to be able to talk to him. So I had no choice but to respect her wishes and that was the end of that. Two years has passed and he has seen the mother out in public several times she never acknowledge myself or my children. Just a hey would be nice. My fiancé and I have ever seen the mother out in public and they don’t speak to each other.To me it’s super weird and awkward. So he gets a text this week saying HE is invited to the child’s birthday party. My children and I were not included on this invite. So how should I feel about the situation and the birthday party? Should I be ok with him going without me and our children? How do I get a positive place with this if there is no respect for our family?.
