I told my friend that a guy didn't like her. I like him so I didn't want her to go after him. I feed bad though because he might have a thing for her.
What do you think you are going to do, are you going to talk to him and find out?
I guess to make things right, I'll find out and if he says he does like her, I'll just do what's right and try to get them together.  If we're not meant to be then we're not meant to be.
Or you could find out he has a thing for you!  I hope either way that it works out for all of you.
