Dead beat dad returns after 20 years of on and off contact? Advice anyone?

Long story short: my mom and dad divorced due to
differences in marriage. He started hanging out with
the wrong crowd, which landed him in jail a few
times and out of a job. My mom got tired, they
started mistreating each other, then it led to
divorce. After the divorce, my mom always made an
effort for us to see our father by keeping contact
with his side of the family, driving us to see him and
allowing him to stay the night at our apartment and
at my moms moms place. Once my mom remarried
he got angry and stopped coming around. He was
also homeless and staying in mission shelters because of the jail issues he had for selling drugs so he was not able to get jobs that paid well.

Now:he's reaching out, and i said to him you
disappeared for 20 plus years. He said your mom
hurt me when she left me. i had to stay in homeless
shelters and i ended up in jail a few times. You have
to let the past go. Im still your dad. He never apologized, acknowledged or even showed empathy over the phone for not being there. He instead said ," why didn't you guys look for me?" Then he said ,"I heard you got married your husband took you my daughter from me. You never invited me to the wedding!" He's constantly blaming me. He wasn't invited because he disappeared again.


Me: I feel he's making excuses. A phone call cost
nothing. He missed every birthday, graduation, and
nany of my life events and struggles. My uncles and
grandfather stepped up
