DF is pretty wealthy - self employed with a property empire. He does odd jobs and some admin, but otherwise his business more or less takes care of itself (he's constantly off on breaks away or holidays with his wife). Despite his abundance of free time, due to living 100 miles apart we see each other maybe 2-3 times a year now, and that's only if I make the journey down there or if he needs somewhere to stay if he's local to me for some other reason.
DF and I have always had a reasonable relationship, but I have never been his priority, even as a younger child (didn't want 50/50 custody, didn't financially support DM with agreed child maintenance payments). Since my 30th birthday, his efforts for birthdays and Christmas have dwindled to the point that this year, all I got was a text - not even a phone call, let alone a card.
This may not have bothered me so much if it weren't for the fact that his DGC that he's so proud to be DGF of, he didn't even acknowledge their birthday this year.
His birthday is coming up soon - WWYD for it, if anything?
