You and me both, girlfriend. Yeah, it's not fair, but that's life.
I have lots of great qualities, but beauty has never been one of them.
Back in my younger years, when I was interested in dating and meeting someone, nobody ever expressed an interest. I was thin, had good hygiene, was well-dressed, had lots of platonic friends who thought I was friendly and fun, I was gainfully employed, intelligent and great at making conversation...but guys walked right by me like I was invisible, And as the years passed, nothing changed. Didn't matter what I did or didn't do, men simply ignored me. Other than a few men who were interested in me for my *money,* my dating life was like a wasteland. So what do you do? You can't FORCE someone to want you. You just deal with it and move on.
I learned to put it in perspective. I've been highly successful in almost every area of my life except for romance. So...I figure when you only suck at *one thing* in your life, you're doing pretty good. Things could've been a lot worse. I've found happiness in other ways - my platonic friends, my pets, my home, my job, traveling.... and I have to say I don't even think about romance anymore, except when it comes up in conversation (like in your post.) I haven't thought about dating in literally years.
I get the feeling you're young. So don't give up hope. You may yet find someone. But you may not. People who say "there's someone for everyone" are wrong. They just say it because it sounds comforting. There is NOT someone for everyone. Millions of people who'd like to find love are single, or with the wrong partner, which is worse than being single. You have to find ways to enjoy your life whether you're single or in a relationship. This way - if you find someone great, if you don't, it's still great.
