My mum lives in hervey bay which is a real nice spot I wanted to move there once my fiancée finished his apprenticeship which would be the end of this year bit he doesn't even want to do that... And he's heaps worried about how would we pay off our cars and save for a house and all that if I had the baby ?
Most car loans are only 5 years so by the time the bubs is ready for school and costing more than you should have them done. Thats how I feel about our 25k personal loan anyway, we only got it beginning 2010 and its a 5yr one. If you don't have a mortgage than you are in a better position already, rent is cheaper than a mortgage, and saving for a house can wait till maybe bubs is in school and you can work more?

Your fiancée sounds a little selfish to me also ..... jst based on what you've said.
As others have said, follow your gut, the decision is yours, not your fiancée's to make. If you decide to go through with it and the fiancée walks out, remember you don't have to do it alone, everyone on bellybelly will support you and i'm sure your Mum will too. I was petrified of breaking the news to my Mum because she'd been so vocal about us waiting to have kids till we were financially ready, but in the end she is crazy for baby and crocheting him cardigans and spoling him and he isn't even out of my belly yet! Her reaction was "well your a big girl now, you will find a way to make it work" (i'm 24 btw i think it says so in my sig), and "hundreds of thousands of people make it work, you can to." Which was not what I was expecting at all out of her! So you never know until you tell her.
