Should I have anything to do with my parents?

Was he really a father. No one should have to take that abuse. Sounds like you try and please them but its never enough. I was the same way. But you have to live life for you and your kids now they don't need to be around the abuse and neither do you. If you feel you absolutle ned to tell him happy fathers day (which doesn't sound like he was much of a dad ) then call him and if he starts in on you hang up. Your in total control of the situation that way. Live life girl believe me im 32 and found out the hard way that life is to short gotta live for you and kids. Be happy
