How can he chose his girlfriend over our kids?

I'm PISSED. We have a lot of smurf going on where we are going to court a lot and meetings.
Last month he told me he was going on vacation with his girlfriend this week, that was fine with me then, two weeks ago we are informed of a meeting we MUST be at next week, ok I told him about it because i got papers before he did, giving him way more than enough time to cancel his vacation with his girlfriends family (he has no more vacation time off work now) so that he could go to this meeting and go to court the end of the month.. Well he decided to use ALL his vacation and personal days to go on this vacation with his girlfriend.

HOW on earth is his GIRLFRIEND oh and WRESTLING more important than his CHILDREN???? He KNEW he had no more time off for this and he will get FIRED if he takes it off. i am SO pissed off at him for this.

I just don't know what excuse he is going to tell his lawyer, if i should tell his lawyer AND out case worker the real reason, since this is showing he doesn't care. I am so SO sad for our kids. This isn't ALL he has done, but it's the latest  

sorry for the rant and rambling, i just have no one to talk to about this.

My son's egg donor did the exact same thing. People just suck... that's all there is to it.

yes. yes they do.
I hate him SO much.
I question daily why i stayed with him so long for!
