Is there any point in confronting a crappy parent?

I don’t have a good relationship with either of my parents. My dad left when I was 12 and, in short, has not been much of a parent since. It’s hard to summarize but enough things have happened over the years that I just see no real point in trying to maintain a relationship with him. He has never been abusive, but he has made it pretty clear that he doesn’t give a shit if I live or die.

Perhaps his only act of parenting since then occurred when he bought me a cell phone for my 18th birthday. I’ve been on his family plan ever since. He recently said he wants to take me off because he can’t afford to pay for it anymore.

This is completely fine with me, since I am an adult and it’s my responsibility to pay my own bills. The problem is, the money thing is just untrue. He and his wife have two houses, horses, nice cars, take great vacations, etc. So, I guess I am interpreting this as another situation of “I don’t care about you enough to pay for this.” (Which might be unfair.)

So, I’m wondering, is there any point in communicating this to him? He has been a non-parent and basically an asshole for so long that I can’t imagine anything I say is going to change him. On the other hand, I am really hurt by his many years of selfishness and neglect. I know that someday he will no longer be here and I won’t have any chance to change our relationship, but I have also pretty much given up any hope that our relationship will ever be anything other than a few phone calls a year with me silently resenting him.

So, older and wiser jellies, what to do? Send an angry email, or meditate on this and accept it for what it is?

Also, even though this is social, please be nice. This is not an easy situation for me.
