Well hon, if you really want this marriage to work, you and your husband are going to have a real good and serious talk about compromising.
We can't all have our way in a relationship nor can we always be the ones giving in so that's where compromising comes into play.
It seems you have several issues to work out so find a day, sit your husband down and have a really really good talk with him.
About going out and having fun, could you not try and find a day a week or one day a fortnight and meet your friends and just really let your hair down and have good clean fun? It might not sound like alot but it sure beats staying at home all the time and moping. Spend that one day indulging yourself, dolling yourself up and having fun.
About the money, I think the both of you should really start a savings plan. Maybe put aside 50-100 dollars a week in a fixed deposit account so while it might not be a huge amount of money, it is still money for emergencies or a rainy day.
Your husband will also really need to come clean with you on why he wants a baby. Having a baby is a huge responsibility which involves not only alot of attention but your finances must really be in order and should not be done simply 'because'.
The decision to have a baby is also very much yours and if you are not ready, you have to make that really clear to him and tell him maybe when your finances are more in order and when things are more stable, you can talk about it again.
I hope this helps a little. If talking doesn't help, you might want to just take some time off and maybe take a short break so the both of you can really think things through before talking again.
Good luck hon and let us know how everything goes. *hugs*
