That is a really good way to look at it! I had never really thought about it, but I can really relate to what you are saying.
I would be interested in guys that either seemed to like me or that I thought might be willing to "lower themselves" to date me, especially in high school. They were generally terrible choices though, often drug addicts or something similar. I never got into serious relationships though, because even though a few showed interest, I would get a terrible feeling in the pit of my stomach and I just wasn't comfortable with it. Around age 19 I decided I would rather be alone than with someone who treated me badly or used me. Then at 21 I met my fiance', and suddenly I wasn't settling for the only guy willing to talk to me, and he didn't seem to feel he was settling with me. We have so many things in common and just love one another. He's smart, funny, kind, and I honestly believe he'd do anything in the world for me, and it's all mutual. That's the kind of stuff that makes it worth the wait.
It's great that you have also realized your self worth, and I hope you eventually find the one who really is perfect for you. Everyone deserves that!
