Why is he doing this?

This can't possibly be the whole story. Did you two discuss children *before* getting pregnant?

I don't know what to tell you to do but if it was me I would have my baby cause I know it takes two to have a baby and if he doesn't want to man up and assume responsibilty then you can always go for child support but thats just me.I know it probably crushed you when he said that to bless your heart and your baby deserves to have it's dad,but you should be a great mom as long as you love that child and be very generous with your huggs. but ask him if he is scared of becoming a father. if he is then let him know that it is easier to be a dad than it is to be a mom so you have more stress on you than he will

He sounds like a real special guy. You need to sit him down and make him talk to you. Ask him why he feels that way. See if he would be up for going to speak to a counselor.

start with asking him why he thinks he wants a divorce , are the two connected etc.

wow - he is telling you one of three things - either he is terrified to become a father, doesn't think you will be a good wife/mother or he's seeing someone else

hopefully it's the first one and it will wear off . .. I am so sorry
