Anyone else feeling like this?

So for the past couple of years my dating life has majorly sucked. I've been dealing with multiple situationships or quick romances that don't last more than a few weeks or months. It just really seems like no guy wants a serious and lasting relationship. I'm not sure if it's this generation, living in a college town, or maybe it's just something about me.

Lately I've been feeling like I'm cursed to be alone. I love seeing happy couples but the more I see people in love, the lonelier i feel.
