Boyfriend has debt and bad credit?

My boyfriend and I have been dating a little over a year now. He is nice and fun to be around. He wants to get engaged this summer in which I have mixed feelings about. Here are my mixed feelings: he is really nice, we are both teachers meaning we will have time together with a future family, we enjoy each others company and friends. On the other hand, I'm concerned. He has $17,000 in school loans, $2,500 in credit card debt, and an outrageous interest rate on his car loan. He barely makes it check to check. I have no school loans or credit card debt. I have money saved and a high credit score. I love him but can this legally affect me? Will this cause arguments because he won't be able to contribute to us as a family since he is barely trying to hang on for himself? This is a emotional vs practical situation. I'm not a gold digger I just don't want to put myself in a nasty situation. Anyone have experience with this or know anyone in a similar situation that can relate??
