To: I need help. I think I’m completely in love with my best friend
Me: If you do nothing, you retain your friendship with him, but nothing more and is that enough?
If you tell him about your feelings for him, it can go either way, he can become your lover, or he can put you off (hopefully as kindly as [possible) but you might lose that friendship, which, if you are young enough, you can find with someone else.
If I were you, I’d go somewhere where it is quiet and you can speak together without being overheard and lay it out, in the easiest way possible, or if you find it hard to speak to him, write him a note and give it to him and ask him to talk with you then and there and clear the air between you, so you know where you stand and if there will ever be anything else between you and if not, why not.
You could say: For you, he is the one you want in your life and for your future, a romance and love, over friendship and nothing else.
You have fallen for him big time and you want to know if he has any feelings at all, for you.
Sometimes the most obvious things are not obvious to those who are at the pit face and perhaps he needs a push to get him moving in the right direction and for you.
If you were me, I would ask, on the basis that “Nothing ventured, nothing gained” and I would want to be first in his life and not left out of it, without a fight and damn the consequences – you fight for what you want and that is why you will always be successful.
Good Luck
