I(f37) and my bf 36m had a hudge argument, because he celbebrated with his wife and mother in law, mother in laws name day. He and his ex wife have two small kids 3 and 10y.o girls.

His excuse every time is that he wants to spend time with the kids. Every time this is his excuse.

When they go to vacation together, when they celabrate something, they took trips together. He says that kids dont want to go with him only, they want his mother and cry about his mother. Will i be the ahole, if im not ok with that?

I just cant find enought arguments, except my feeling of left behind, feeling of being the second one, and the feeling that he doesnt care how i feel while he spends his time with her.
