It happens to everyone, being misled that is. People don't like to get to close to someone that comes off complicated and aware of what they want in a relationship. Because it conflicts with what they were trying to get into when they were getting to know you. At least that's the feeling I get when someone just ups and disappears. The only thing I can say is just take the vibe that you get off these guys and just remember when a situation like that happens again (hopefully it wont) and be able to read that person and know what to do the next time it happens. Me personally I just want to meet someone I like, likes me back, and knows how to be patience with things that go on at the beginning of a relationship.
