We all make mistakes, it doesnt appear that you handled this situation well, perhaps because you are grappling with your own issues of sexuality
i wonder why you need to contact him ?? are you hoping to tell him you wanted him as a b/friend ?? or do you want to explain that you were confused but now know that you just want to be friends and miss his friendship
perhaps you should sort this out in your mind first and then i agree with sara3, find him on the social sites.......................
good luck
