i haven't read everyone's replies but here are my thoughts:

1. You say you want to have another baby 'with him' - if this is going to tear your family apart then you will not be having a baby with him, you be be a single mother - are you willing to do that without regretting this child or your decision later?

2. It is a decision you BOTH need to make, while i agree that it's your body and majority your decision i also feel that if it's not his choice and he's going to treat this child differently it's not going to be a harmonious upbringing IYKWIM.

I would strongly suggest sitting down together and discussing things, i can completely see where he is coming from in the sense of not having the $$ to support his family, i've come to realise that even when my DP doesn't show it he is under a LOT of stress to provide for us and that initiself can cause a lot of issues without adding to it.

I'm not saying your wrong for wanting this baby, i think everyone learns to adapt and cope and love a child and that is what a child needs, but you also need to go into with a clear head knowing what you can and can't do.

I also think if it was such an issue for him then Birth control should have been sorted, if you've been through 1 termination already then that should have been on his mind.

I hope he comes around and you get your much wanted lil bub, but either way there is plenty of support here for you.
Talk it out and go from there.
