Pregnant and alone

So I am currently 32 weeks pregnant and the baby’s father abandoned me at 21 weeks. I caught him cheating and after that he said he couldn’t do this anymore and left. Never asks how the baby is or how I’m doing and never shows up to any appointments. He’s out there living his life like we don’t exist and it hurts instead of trying to fix our relationship he’s out there going out with different women. I’m so broken by this I don’t know what to do anymore.
