NB, it's true what PDT and KS have said about God hearing your prayers! We just dont always see the answers or choose to accept them. I've spent months crying and pleading to God and praying to everything and anything. I swore he gave up on me... I too cried in the middle of night, hoping God could make H fall back in love with me...
When my son was born three weeks ago, i realized that God did in fact answer my prayers and is giving me stregnth to get through this no matter how my sitch may end up. Sometimes we just have tunnel vision and dont see god standing on the sidelines.
I also commend you for not walking away and giving up so easily. Yes, this site is all about helping us "Save our Marriage" and if you walked away from working on it or just gave in... then you would be just the same as your H? Right?
Keep your chin up and take care of yourself... I know how you feel and how hard it is to be pregnant and going through this... Make sure you are resting and eating and taking care of yourself and the little one.
Keep posting, you are getting great advice and will meet so many supportive people on here that will help you no matter what road you and H will go down on.
