You have begun to learn the gifts of crushing.. you don't like to just be alone anymore, you are starting to wonder how being alone with just that one person feels. and of course you want to touch. but you still have alot to go before you can handle the big time crushing... maybe for life.
By the things you told me, you guys are good friends. No need to panic though! Friendship is important... Try to be a little bit more flirty... Give away a few more hints on liking that person. Maybe... If you really are good friends, you should just tell your feelings! Some people say it hurts your friendship... But you falling in love didn't already then? Keep your head held high and do what you feel like doing!
