♥Erin has a crush on Brandon♥

I like this guy and people have told me that he likes me too. I catch him looking at me in class and in the hallways. The problem is, I don't know if he likes me anymore. You see, he hangs out with this group of girls in a certain class that we have together. Well, I overheard them talking and I think he's going to do something with them this weekend and I know for a fact that two of the girls that might go with him used to like him. I'm a very jealous person, and when I heard this, it nearly broke my heart. Can anyone give me some advice? I'd really appreciate it. Thank you.

P.S: I would ask him out, but I've had really bad experiences with asking guys out and I'm afraid to. :(
