Childs father is an asshole

So throughout my pregnancy I haven’t seen or spoken to my sons father. Last time I seen him is the day after I found out I was pregnant. So i wrote him on Instagram a few days before I gave birth to ask if he was going to be present for the birth or still be an asshole..... no response. Then I wrote him the day after and I said “ you’re pathetic you missed the birth of your first child, anyways you have a son.. I’m telling you just so you can never say I didn’t tell you “ so it took him 5 days to reply and he’s going to say who is this 😑 I replied and guess what.... he blocked me. He’s a loser and I can’t believe he’s my sons father. I’m happy I got my son out of that toxic situation. My son was the only good thing that man ( more like a BOY) gave me. I’m hurt for my son 😩😩
