What would you say?

My fiance and I have been together for almost 3 years now, we got engaged this past November and our baby is due this coming November.

We've recently been approved for a mortgage and based off of our income, we don't qualify for the first time home buyer credit because we make too much money combined. I agreed to not list my name on the mortgage so that we can qualify for the credit and now, I'm having second thoughts. We got into a huge fight tonight and he basically told me that he "doesn't know if he's taking me or the kids with him when our lease is up in the end of August." I got pissed and told him, I don't need him or this house. I can do this on my own and he can go to hell. I also told him, I refuse to move onto the same street as his nosey ass Mother which he's mad about.

I hate to say it but I'm seriously regretting this baby and the decisions I've made up to this point. We weren't trying to get pregnant and we seriously considered abortion until we mutually decided to move forward with the pregnancy. I'm at a loss now, I want to know what you would say in a situation like this? I know this is long but I'm lost and I'm pissed.
