Is it bad that I'm getting tired of my boyfriend?
What has made you feel tired of him?
He makes fun of my situation saying that I'm just a girl, and that guys in college have more fun than me.
People generally feel a strong emotional attachment to their partner. If you do not feel that anymore you should think about breaking up so both of you can move on.
I feel like I should do that sometimes. I don't think I like him very much.
I think you should should seriously consider breaking up with your boyfriend because he seems to be making you feel bad. There's no reason to stay with someone that you don't have a connection with.
