I need help

I'm 32 weeks pregnant with a baby girl and I cheated on my husband but I told him and he wants to work it out and gonna get a DNA test done but im pretty sure she is his . But he keeps throwing it up in my face. How can I make it work if I'm jus depressed and crying 24/7. But when he cheated on me (he just paid for head) I don't bring it up. I'm jus so hurt and depressed it's bad where I still haven't done anything to the nursery. And he be texting me other girls photos from fb or Instagram like I'm not good enough
