Problems with my Dad?

If you're an adult and you don't even live with your parents I'd just be kind when you see them and be planning my own future. You already know you don't want to end up like your dad so use that motivation to get a good education so you won't have to send your kids away over an inability to care for them.

not much you can do but pray he changes

Listen up, and listen real good here-

You are not to blame here for your fathers issues, or for you living at your grand parents house here! Your Dad has issues that have been with him long before you

were even born, so how can you hold yourself responsible for the choices that HE

has made in his life?

I'm going to be blunt here, your Dad is not a real man, he's a little boy who thought he could play a big boy game by ejaculating inside your mother, he really has not been a father to you! Real men step up, and he should have have saved up money the second he knew she was pregnant, even if it was an apartment, it still would have been something! Real men provide for their families, and most importantly he has not been there for you for anything while you were growing up.

The fact that he had the audacity to say that "what have you done to me", it speaks volumes about his severe lack of character! If it were me I would have called his bluff by saying "tell you what lets compare notes, I'll tell you what I have done for you, and you tell me what you have done for me as a parent"! I can assure you the idiot would have nothing to come back with, because you can't create something if it doesn't exist.

I'd write him off if I were you- He's never been a father, hes a sperm donor! No harm no foul, you move on with your life, and hes free to burn his to the ground by drinking etc.

 You should do what you can to repair your relationship and if that doesn't work out, so be it. If he wants a good son , he should be a good dad.
