It sounds like you need to work on protecting your boundaries before you get married. If you marry a really nasty guy, he may end up spending all your savings, making you liable for half his debts and live off you for as long as the ****ed up divorce laws will allow him to. Then you'll NEVER get rid of him. If you still have trouble protecting your boundaries and get married anyway, I recommend a prenup that protects your assets, protects you from his debts, his spending and protects your future income. Guys these days frequently quit their jobs after they get married (in fairness to any guys reading this, yes some nasty women do this too but I wanted to point out that it is commonly becoming a nightmare scenario for women too). Then their wives, even if they weren't planning on it, end up being forced to work because SOMEBODY has to. Then the guys claim for spousal and child support (if kids are present). They don't even have to be a stay at home Dad or do any of the 'wifely' duties that stay at home wives do.

Marriage is not all it's cracked up to be. Be very, very careful, particularly because of your tendency to let guys walk all over you.
