Doh, I hope we haven't scared off the OP. I wanted to elaborate my original statement in that the psychological effects when helping someone pay their debt down are very different when you're not married vs when you're married. When you're married, you share all the debts, no matter who's name, because you can easily get pinned for your spouse's debts if things don't go well... so they become both your debts, instead of just his debts or just your debts.
Paying someone's debt for them when you're not married is the tangled web... unless that person is paying you back or something, well, honestly, I think there have been volumes of hardback books written on this topic. It becomes enabling, to put it in a nutshell, and changes your dynamic completely.
What you're wanting to give your boyfriend is the life gift that YOU received when you paid your debts down, because you love him. But you giving him that is not going to be the same as him earning it. Teach a man to fish! Hopefully, by now, he's expressed that he doesn't want you to pay them... and in that note, if he IS ok with you paying them... well, that needs a red flag, as well as his current and past spending habits.
You're obviously a very compassionate and loving person, and I'm sure you've heard the saying about communication in relationships, so talk with him about financial goals, because that IS a big part of marriage, unfortunately.
