It depends...Do you really love him? You gotta think, you could lose your friendship...But if your that close, that wonts happen....

I was and i'm still kind of in this situation. First you need to see if it's really love or just obsession or lust. After that see if he shows more than friendship towards you. In the past i used to not tell my feelings... but u have nothing to loose... tell him u don't want anything to change if he has different feelings towards you and then tell him how you feel... i wish i cud help you more but the next part is the chance part. I wish you the best!
