It's not really relevant if you're married or not if you both plan to own the property. You would apply for the mortgage together and they would look at the full picture for both of you. You can't pick and choose.
It sounds as though it will make sense to wait a couple of years before you buy regardless. If your boyfriend had trouble managing his money in the past, he should demonstrate to you and to the lender that those problems were in the past and a function of something that is no longer a factor. If you own a house together and he still struggles with managing his spending that could be very stressful and it could throw your home into foreclosure if you can't cover his portion of the mortgage payment which would kill your credit. In the meantime, you'll want to have steady reliable income in case he doesn't have a job or has a financial crisis of some sort.
That's probably not what you wanted to hear, but that's likely what the bank will tell you anyway. Good luck!
