Why would a dead beat dad returns after so many years and try to play the father role now that you're an adult?

I am very wary of him because after my mom divorced him when I was 7 due to him being on drugs and abusing her. He stopped contacting us completely. I would hear my mom on the phone calling him, leaving him messages asking him to see us. He'd make promises then never show. Then I finally seen him again when I was 23. Then years later after that. Nothing ever consistent. Calls every once In a blue moon and barks orders like I'm a child stating ," I worry about you. As soon as you get off work go straight home."

Blah blah yet where was this concern years ago. Then he got mad at me for not wishing him a father's day. I haven't wished him a happy fathers day since I was 7. He hasn't been here. Then I addressed it he blamed my mom saying he didn't come around because she remarried after the divorce (she remarried 3 years later). And said he was homeless because of the divorce and blamed my grandma saying she was evil that's why she's dead now. But come on who would want their daughter to stay married to a man using drugs and abusing her? My mom divorced him because she said she found drugs in my stroller from him doing drugs and making deals. She said I could've gotten taken away if the police caught him.

Because he's getting old and needs someone. Basically for selfish reasons
He has regrets
I'd be wary of him and his intentions to not sure why he'd come back

My mom was not and isn't isn't bitch. After my mom divorced him he started staying with his mom. While he was staying with his mom he stole from her several time. He also went to jail for drug possession. Yes my mom and dad had issues but there is no excuse for him to disappear from his kids regarding if my mom was a bitch or not. there's no excuse to abandon your kids

If you're going to come on my post saying things about my mother being a bitch or bitter your comment will be deleted. I've already stated in the update what I know and have seen for myself. There is no excuse to abandon your kids!
