I don't think all men don't know what they want, just the ones you have dated. I think as people grow they learn what they want out if life. I'm sorry about your releationship. Being with someone who can't love you is rough. I dated this girl for a while and she was bisexual. Somewhere in the middle of the releationship she decided she didn't like men. It sucks but some people just don't work together. I think there is someone out there than can love you. Just because people aren't flocking to you doesn't mean you won't find someone that cares and loves you. I would suggest working on yourself and building up your self esteem. I have problems with esteem too and people don't like other who aren't confident and sure of themselves. At first they give you compliments, but after a while they get sick of being your personal cheerleader and drift away. You have to learn how to love yourself and be happy with who you are.
