My best guy friend and I have been friends since what feels like forever. I have never dated anyone before and mow that we are juniors in high school I have suddenly started having feelings for him I have never had before. How do I tell him I like him if I am afraid of ruining our friendship?

Well, if you guys are close and spend a lot of time together then chances are, he likes you. Its rare that guys just want a friendship with a girl. I'm not saying it doesn't happen, but trust me. And if he doesn't like you back then at least you took a risk. That's healthy, speak your mind and if it ruins your friendship, then maybe the friendship wasn't meant to be.

You don't have to blurt it out. There are little clues you can give him. Cookies you bake yourself on his birthday or any occasion. Ask him if he likes your hair a certain way, your new shoes. Ask him a hypothetical 'can best friends fall for each other?' Or what his ideal girlfriend is like - as you are on your way somewhere and don't even have time for an answer right then.

Thanks! Do you have any other things I could say as subtle hints?

Complain about what a lot of guys are like and say, 'I hope I can find someone like you someday' or 'I wish all these guys were more like you.'
Draw a funny picture of him doing his favorite thing.
Pick a flower, curtsy elaborately, and say 'For you my liege.'
(Don't give him something you buy.)
If 5 or 10 subtle hints don't work over a period of about 2 weeks, you may have to say something like you feel a little funny being alone around him now, because you are starting to really like him. Again, say that as you are leaving so he doesn't have to respond. It will give him time to mull it over.
