Damn, that really sucks mate, sorry that she broke up with you
Well, I know this is going to sound horrible but from the sounds of things this seems like the best way possible that you could have broken up with her, truthfully - she still wants to be friends with you, and is supportive of you, as is the rest of your friends.
I'd advise to just try and cruise the wave here, accept that you two had a thing, but are now just friends - hey, at least you can still be around her

who knows, maybe some day in the future things might possibly kick off again?
Also, bare in mind that things could be a lot worse, it seems like she still cares for your feelings and tried to break up with you in the kindest way possible... I too had a similar situation (had girlfriend, thought that we both loved each other, girl says she doesn't after a couple months etc etc, I made a whole thread on the thing) eeexcept in my case she wasn't kind about it, she dumped me over an email (which never arrived so I found out through FaceBook), and she started going out with one of my best friends less than a week later - it also turned out she was cheating on me as well, which I had a suspicion of after she broke up with me which was later confirmed...
So, yeah! I'm glad at least that that didn't happen to you ^^'
Life has its ups and downs my friend, and breaking up with people you love is just one of those experiences that one must endure in the end. Accept that it happened, remember the good times with her, and look forward to the good times to come
