friends?

I think I  made the mistake of letting a good friend know I had developed some sort of a crush on her..here's the sequence of events: we are both in respective relationships, and what began as a friendship progressed into some (harmless) flirting....then all of a sudden the flirting became intense and she started losing it...we came around to talking about it & I reluctantly admitted to having some feelings for her ( I had NO intention of acting on them!)as a means to salvaging our friendship which was paramount to me.. We continued to talk, but obviously something changed & I guess I missed the camaradierie we used to share, and also noticed that she was VERY withdrawn from me..(which is justified)..anyway, that was a long time ago and everything was fine, but I have been having some issues(totally unrelated to her!) lately and I happened to take out my frustration on her - wrong yes, but friends do that, right?? This freaked her out & she has chosen NEVER to speak to me again as she is convinced that I am in love with her! I feel like I was just dumped by a friend ( something that has never happened to me before!) and I am not sure whether I should be angry or indifferent. The situation sucks and I need some words of wisdom to either get thru to her or get thru this bizarre situation..
