Move on?

My baby's father left us when I was 12 weeks pregnant and since we all know I'm due next month I haven't heard from him since he left.. I still sit around with hope soon I'll hear from him, but he said hurtful things like denied our child. Begged me to abort, posted on Facebook that my child wasn't his. And was talking to multiple women threw messages.. So I don't know if it's even worth sitting around and crying for.
