Just marry someone who a) deals with their shit and b) doesn't drive you crazy. If you're not sure your love interest is doing "a", find a mouthy asshole you trust and mention things about your relationship to them. If they don't convincingly criticize your love interest (or you) then you're probably ok to get married. If you don't yet know what drives you crazy: stop. You are too young to get married.
