My guy friend liked me and I liked him. Then just a few days ago he started liking my best friends. He asked her out but she said no. She doesn't know I like him. What should I do?

Just try to get over it.

There is nothing to do. I guess he didn't like you as much as you thought.

Of course you get over it because he likes someone else better. Even though he got rejected you keep your business to yourself. How old are you three?
