It all depends on what you are looking for. Some people in college haven't quite hit the maturity stride where they are looking for something serious. They go from one guy to another and are having a blast doing it. They are attracted to confidence in guys even if they are usually big headed. Some continue that through college. Alot of them get tired of it eventually and then want something serious. It all depends on the person and their experiences. Some mature quicker than others.
I met my ex in college when she was a junior. She fooled around enough and was not getting what she wanted so she finally wanted to settle down and take things slow. I was a dick and a little more deceptive than the others, but the fact is that there are people like that out there. They just don't have a neon sign above their head saying what they want or how mature they are. That's why as you get older, we go through more people and more dating because if you don't feel that connection off the bat or seemingly little things are enough to call it off, you just continue on. You want to get to know them but there isn't any time to waste.
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
