@reminelle,
Your weight is normal.
You are tan colored? So what?
It sounds as if you may have some self esteem or self image problems.
You said you don't like him in your title. Why then would you go out of your way to meet him six hours away or even if he came there? Or is that a matter of your not having a crush on him? I read you as completely uninterested unless he is the last man on earth for you.
Also, college is hard for the majority of students. I don't mean to be mean when I say all this, but sometimes when people are growing up, and at 22 people still are in the process of it, they don't develop curiosity/interest about others lives as much as they worry about how people think of them. It's a fairly normal phase but can be in your way regarding what you would like to happen, that is, getting people to like you.
