Trying to adjust but anger rears its head

I asked my husband today why he was driving nine hours for 10 minutes or so of time with his almost adult daughter when he admitted "they don't care about this family at all".  He said he was doing it for himself, so he knew inside that he has done what he could to be a good father no matter what. 

For "kids" who have not given him the time of day the last couple of years and who totally ignored him this past Father's Day (and last year too if I remember correctly) - totally blew him off with no contact, "kids" who are old enough to know better, I think he's wasting his time personally (as well as money we desperately need). 

Part of me is trying to understand where he is coming from and part of me feels a bit betrayed because we agreed to discuss things together and this was definitely not a mutual decision.  I feel like he's putting them before our own family's welfare and security, and shredding marital trust, and that it won't make a darn bit of difference to his kids at all.  It's one more piece of resentment I feel adding up.

I started reading Divorce Poison today.  I've been wanting to read this book for quite awhile now but after all of this, part of me just feels numb to all the poison anymore because at this late stage when the kids are coming up on adulthood, is it really going to matter?  I feel like it's too late.

Guess I still have a bit of "mad" on.  Hearing him talk to his mother on the phone today about his upcoming visit just brought all the anger back again.  The spiteful part of me thinks that if he spends this visit next to the ex in that stadium, after the hell she's put us and all the kids through for 15+ years, he can stay up there and not bother coming home.  Yeah, guess I'm still mad.

My birthday is Saturday.  Happy Birthday to me.  Not.
