Thank you SarahBoo and I've done it. I've sent the email to him just few minutes ago.
here is what I sent to him.
I've been trying tell you this for awhile now but I've always chickened out. I've told myself that this year will be a year new strengths and moving forward. I know how we are very best friends and I don't want to jeopardized it for anything. Also, I don't know if we've ever talked about this
happening.So what I'm about to tell won't change that on my part unless you want it to. You see I've fallen in love with you. I don't know when exactly or maybe I've always have. Everything you do; from the IM of hey, there is a game sale on steam or whatever. Or even silly little things like owning a very very very small part of an island gets me feeling better on a bad day.
All that I know is my heart jumps a beat whenever you are mentioned or whenever I see you online. When I come over and hangout, it just make my week a whole lot better. I want to feel your warmth and heart beat as I lay my head on your arm as we watch some show or movie.
I just thought you should know. I'm still wanting to be close best friends. Please whatever do, don't respond in anger. Take your time if need be. Also if you share theses feelings, it won't make you gay at all.
