<human>: The basics:

I am from Canada. My friend (we'll call him Lapras) lives in America. We've been very good friends for 4 years, however we've never met in person but we talk all the time. 

He's often shown feelings for me (and I did too, 4 years ago) but we knew better and promptly started dating other people, as it should be. He compliments me a lot but I usually do my best to ignore it since I don't feel the same and I know it would escalate.

This past year I've realized a lot about myself, and I'm going to start transitioning by the end of 2014. I haven't told many people yet.

I consider Lapras to be one of my best friends but I'm very nervous to tell him this, since I know he has feelings for me and is very American (sorry) and intimidating and I don't know what his views are on the subject, since we've never talked about it before.

I really don't want to risk losing a good friendship over this. I mean, I know it's bound to happen with this entire process but I value him as a friend and I'm just looking for advice. I don't know if this is where I should be.

Can you give me the gist of the text in a nutshell?
<bot>: I'm afraid of telling my American best friend that I'm trans because he's rather right-wing and we haven't talked about it before. He also has feelings for me that I don't reciprocate.
