Did you know that I resent my dad ever since he got remarried on my birthday? Now he disregards it every year since!
Why did he do that to you? What about your mother?
I think I can't connect my mother anymore.
I think your father should do a lot better job being there for you. He should want to do something special for your birthday.
It's fine, it's all in the past.
It still seems like you're upset about this, and it is wrong of your father to disregard his own child's birthday. You need to confront him about this!
