If you can get your freind to ask him if he likes you, if not try to become good freinds with her and go up from there!
I like a guy but I don't know if he likes me back. He knows I like him but he likes my bff and I don't know if she likes him too. I need to know how to get him to like me and quick, before she decides if she likes him?
I'm struggling with this at the moment too! If you text or talk online, try adding an 'x' at the end and see how he reacts.
If he says anything just say 'oh sorry, I do that sometimes in my messages' because a lot of people do that so it won't seem weird.
Also, make sure you take an interest in his interests! The guy I like plays a lot of basketball, so I always make sure to ask how his game went and if they won. If it's just training, I try to say 'aw I'm sure you were great' or something.
Try not to complain about stuff to him. Its off-putting and makes you seem like not a very nice person. Of course, if you start dating, you can vent a bit to him, because he should want to support you and listen to your problems (you should listen to him, too) but try not to go too ott.
Like if there's someone you really hate, just say that you find this person really annoying, rather than using the word 'hate' - just tone down any negativity. Good luck :)
Addition: have you asked you friend she likes him? If she doesn't, she can make sure she's not giving him the wrong idea, and can even try and make him notice you!
Sorry, it's going to be very unlikely. Unless your friend really crushes him, then it might be impossible. Usually when guys have a crush on one girl, they don't give up on them unless one, they are shallow, or two, there is no hope with their crush.
Remember, you can't force someone to like you. No matter what you do, it's their decision entirely. I understand that this can be hard to accept, but the sooner you do, the sooner you can make better use of your time.
Sorry to sound kind of pushy, but I'm trying to be honest.
