Student Exchange Programs

I really like this guy, but he doesn’t know. He likes another girl- this exchange student that is going back home in July or August. He knows who I am, but isn’t interested in me that way. I haven’t really talked to him at all. I’m pretty shy. I look okay, I’m not hideous, so it’s not like thats a problem. The exchange student isn’t much prettier than me but they have more in common so far because I haven’t talked to him yet.
He likes her a lot, but she doesn’t really like him.
She flirts with many guys; gives them hugs, etc.
