I recently graduated from university. While I was in school I dated my share of guys, except I didn't really "date" any of them. I hooked up with them for months/weeks and it never went anywhere.
The truth about dating in college is that most guys don't want to date; they aren’t looking to be in "serious" relationships. Most of them just want someone to sleep with on the weekends, but they won't hangout with you during the week, they won't help you with your homework and they certainly won't bring you any soup when you're sick.
Of course, not all college boys are like this. Some of them will bring you soup when you're sick and hangout with you during the week. The key to finding these boys, however, is the tricky part. You have to go through the bad ones to get to the good ones and sometimes the bad ones can be disguised as good ones.
The only way to find out what kind of relationship he wants is to contact him during non-hookup hours. If he waits until hookup hours texts you back odds are he just wants have sex with you. You can either continue the hookup cycle or find a guy who wants to be in a relationship.
Don't worry, ladies, dating in the "real world" is much simpler. Gentlemen, this goes for you, too.
