I had a few girlfriends throughout college, all seemed to be like 3 month relationships, and I'd go out with other girls here and there between relationships or just stay single. After college, I decided to just stay single and not even try. I'd go on dates here and there, but mostly I was completely uncommitted. 2 years after college while doing this, I met my wife. We've been married 3 years.
Though I wish I was single more through college, I don't regret anything. That being said, it's when you're not looking for anything that you're mostly yourself. You're not trying too hard or going out of your way to impress. It's during this time that if someone is really into you and you're into them that it's more likely to be something worth pursuing.
Bottom line, don't force it and just be yourself.
When you're young, get it all out of your system so you have no regrets when you settle down. Always go for the girl you're after, even if you don't think you have a chance. Worst that could happen is you get rejected, and then at least you know.
