I swear I am a magnet for people who are unavailable to me.

Why is it that every guy I meet is unavailable... Doesn't matter who he is there is always something that makes him unavailable.. Its very frustrating. Whether he is already taken, unstable, or god forbid not wanting a real relationship. Did we forget what the point of dating was? Cause I thought it was to meet people and get to know them in the inevitable goal of finding one single person to be with. So if one "dates", but does not want a relationship, then what do they want? What are they looking for? what is the end goal? Why are they dating? I am frustrated.....Just talking out loud..
