Is this an childish is there anything I should take out?

Hi all, I haven’t spoken to my baby’s dad since July and I just had our son. He said he didn’t wanna be apart of the baby’s life and I’m okay with that. He also agreed to pay child support. I can come off as really mean and rude and I’m trying to be the adult. We’ve gone back n forth n back n forth and I’m exhausted. I want to leave him in 2017, n move on.
