This is long but I really need someone to tell me?

I really need some help please, my dad all my life has been the type where he says he will DO anything for me or my sister, but yet it is always threw back up in my face, when he does help me or give me advice. He tries to pay me money to leave my husband, he has always been very controlling, has to be right, never wrong, and if he says something wrong, then I misunderstood. What I am wanting to know is, well 2 days ago, my dad and I were having a conversation about my 1st stepmom and he and my stepmom now are upset that weve gotten close, but when i was little i thought she was my real mom, until the age of 11 when he found out she was pregnant with my little sister, he said he was marrying the woman hes with now, and i was devasted, anyway to make it short, he was trying to make me tell him the bad things he done to me when i was younger (he doesnt think there was anything bad) so he pretty much said if I was positive about one thing then i would tell him. I said well thats another conversation and another time, and I also said that I was a good person, and i dont throw things up in peoples faces cause it hurts when it is done to me, so he said he wishes we never had conversation, and i said nobody should be mad but they are cause i was talking to 1st stepmom again, well then the straw that broke the camels back was when he said "from one slutbag to the other" and I said dont ever f****** call me again. Well i have dealt with this kinda stuff my whole life and I feel it is time to draw the line, I am done with him. Does anyone think I am wrong or do you agree. I can only take so much mental abuse.
