Thank you guys, I do understand that I need to let it go. But I also want to keep good relationship. I do not want for a court to decide when I can visit my kids.

What bugs me a lot, that she even does not inform me how kids championship went. I did not want to ask, but then what father will I be, if I am not interested.
I do not know how have to I address that. Sometimes she is nice and even caring, and two days from it - cold and ignorant.
