This is for many -- way too many -- guys who can't get their grammar together on their profiles. Are you looking for "someone who takes care of themself"? Then you better look for someone who thinks "themself" is a word.
More generally, if you are a heterosexual man, you should have enough confidence to refer to your future significant other as a female, i.e. "she" or "herself". Referring to the person you want to meet as "they" implies that you don't know the gender you want to end up with, or that you are looking for a polyamorous bisexual relationship in which you'll be dating both men and women. Which is fine, if that's the case. But most of you hetero boys looking for a girlfriend must be so intensely uncomfortable with the idea of commitment that you just can't bring yourself to refer to your dream woman in the singular.
