I (20F) haven’t seen my biological dad since I was 2. He chose drugs and chaos over raising me. My mom did everything alone, no child support, no birthday cards, nothing.
Now that I’m in college and doing pretty well, he’s suddenly emailing me saying he’s sober and wants a “fresh start.”

I responded once, politely, saying I wasn’t interested. He kept pushing. My therapist said it’s okay to choose my peace.
Now my grandma (his mom) is calling me cruel for “punishing a man who’s trying.”

AITA for refusing to let a stranger be a father just because he finally decided to grow up?
