Am I just not meant to find love? it seems no girl is going to love me?

I have never been in love. I'm not mr. relationship. I've experienced heartache but no love so maybe that's why it's so hard for me to find sincerity in girls. I feel I shouldn't put my heart in it because I've experienced heartache and no love. One of my problems is that I can't be happy without some girl loving me. I find something wrong if I can't find anything wrong with a girl because that means she hides real well and is probably deceiving. I know EVERYONE has something wrong so that's why it worries me. I think if a girl seem too good that I should not put my heart in it or let her go because i'm SCARED of getting HURT. I know what it's like to have high emotions and then drop. It really hurts. I'll meet girls who have bf's who would go out with me but because they have an effin bf it doesn't happen. I believe the ship has SAILED and it's not coming back to get with girls I actually like. I'm not picky.
