How do I tell my best guy friend that I like him?

I think that you should tell this boy how you feel and if he doesn't feel the same way then you need to find a man that will feel the same way about you after feeling so close to you. And if he lets that get in the way of your friendship, then he doesnt deserve to be your best friend

If you are sure about these feelings and don't think it's just a one off crush, then the friendship is already awkward. He may not know it but you are forever stuck in the phase were you are constantly thinking about him as your maybe-boyfriend instead of your friend. Just ask him if he could see the two of you together. Don't make it sound like a big deal, but if he asks don't hide it either. If he does like you, hiding it could make him think that he's just imagining your feelings. If he doesn't like you back then you'll have to talk to him about whether or not he's still comfortable around you. If you're really super tight you should be able to be honest with each other.

"The best couples come from the best of friends."If you guys are as close as you say, then this was bound to happen eventually. You've gotten so close to him that you've become romantically attracted. It's only natural. The same thing happened to me once. My suggestion is to take it easy. Don't have a sit down with him and empty out your feelings in one sitting. Just keep enjoying his company, do things with him that find you sitting close to him, maybe ease into a topic and start talking about "something" that you've really loved having all this time. Turn to him, I'm sure you'll be smiling, and maybe put your hand on his arm and move your face close to his. I don't know about him, but I'd be having trouble keeping my heart in my chest at this point.Good luck Kris.

Speaking from experience, harboring feelings like that towards a friend for a long time and not telling them can wreak havoc on your emotions...my advice would be to just tell him. No matter how things go, I can guarantee that you'll feel infinitely better afterwards.
