How do I move on?

I am currently pregnant with my ex-husband's baby; at the time I fell pregnant, we were married, but we separated around the time I fell pregnant. Due to him cheating on me with other guys and lying a lot, it probably didn't help that I was also crazy—not crazy in the sense that I would break anything, just crazy in the sense that I would blow up his phone. Fast forward to today, and our baby is due in a few months. No matter what I say or do to get him to not abandon his child, knowing our baby is 100% his, he tells me to leave him alone and to stop contacting him, as he wants nothing to do with me or our baby, and he has also said he won't be paying child support either.
