Hmm.... well coming out always seems to pose that problem.... some people just aren't going to understand.
Middle school itself is a crazy time. When you go into middle school, you have completely different friends than you will when you leave high school.... I'm not sure why, but you do. I think when you get out of middle school, you're exposed a more accepting environment of everything.... less drama, gossip, and all that good stuff.
All I can really say..... there's a good chance that you would have grown distant anyways. It sousnd like he wasn't always going to be there..... even if you didn't come out, he may have found something else. Give it time, things might change.
If he was as good of friends with you as you were with him, it will get better. Just give him space. If things don't work out, there are plent of people who will be there for you, so you can't dwell over this for now.
I hope that helped....
