Well, I'll start with your story. The first thing you have to remember is that if you were great friends with this girl, things probably won't be as bad as you think. The bonds of a good friendship are hard to break. My advice to you would be to first apologise for what you said and politely explain it was said out of anger and that you didn't mean it (Assuming of course, you didn't). You have to remember to remain calm and sincere during this, to show you truly are sorry for your outburst.

If this (What you said to her) was something you've been thinking about for a while, you need to explain this to your friend. Tell her that you've been thinking about it for some time and that you intended to talk about it, but when the time was right and that the way it came out was never your intention. Apologise for that, but explain how you feel about it. If this causes her to back away, try not to be too upset. Living a lie in a friendship is far worse than being honest. Honesty is the foundation of good friendships (And of course, relationships). If she can't accept your honesty, then your friendship won't last. Try your best to repair your damage, but remember, if her mind is made up, it may be best to give her some time to think. I hope things go well for you, I really do.

Personally I've put my foot in it several times with friends and tried to explain. Sometimes they refuse to listen no matter what. People can get to the point where they've made up their minds so much, nothing will change it. This happened to me last September and I still haven't heard from my friend since. I don't think I will neither. This happens, it can be repaired, but if you didn't deserve it, it might be best not to try. Friends like this sometimes aren't good friends at all.

People have also done it to me, but I'm the forgiving type and I like to carefully think things through. With enough effort and perseverance, any friendship can be repaired, it just takes a little time.
