Going through a breakup

Anyone going through a break up while pregnant? Unfortunately I am with the father of my child. He has been a piece of shit my whole pregnancy and I still have 19 more weeks to go. At first I was trying to hold on to our relationship just for the babies sake but I am sick of being hurt and constantly crying. Staying out and partying, not coming home and possibly cheating. We live together but I cannot be with him anymore, this is supposed to the happiest moment of my life and all I have felt is pain and sadness.

Any other mama's out there like me.
