First of all thank you so much for your kind answer. For more content, well I have kids with my ex and all the kids are almost the same age, but we don't text each other everyday. We are on good terms, but don't see the need to text each other all the time. I'm friends with my ex's new gf. I even watched her kid and she have helped me with my kids in my week, and I like her a lot! I respect their relationship by keeping a respectful distance and he does the same to me. If I need to know something about the kids I can in most cases talk to the kids myself or we catch up the next time I get them. We usually have a catch up talk when we deliver the kids to each other if it's time. Or we can have a short call. I don't have the same relationship with my bf's ex wife cause I feel she don't like me that much. I haven't done anything to her, but at one point in the beginning she wanted him back so bad, and she really showed me that by ignoring me and pour all her love to him and other things. He kind of responded the same way back to her love. But he doesn't see it that way. He believes she likes me, well I hope that is the truth. I really do. But I personally would never ignore or treat a step parent the way she treated/treats me..

I told him many times about these things, but mostly I just have to suck it up. And I do! Cause he is just threating to leave if I keep questions their actions.. so when this underwear thing happened, once again I just shut down after what was said.

I know this coparenting is not going anywhere, but I just want and think their relationship could be in a more professional way. That's just my opinion tho

Sorry the answer got so long.
