I hear that.

It was the other way around for me, though. I hoped to remain friends with my former love and she just axed me completely. Sorry, still a little bitter about that but I'm working on it.

That's the bugger with relationships - it really needs to be a two way deal for it to work.

My small advice would be this - both of you are a little fuzzed up in the head right now and it's leading both of you to say and do things that aren't helpful. Give each other some proper space for about 3 or 4 days - it'll give you both time to settle down and get your heads straight. You've sent her a letter, which I imagine tells her how you feel far more eloquently than speech can right now.

After those 3 days, then approach each other - some thing neutral, like over coffee or something and see what happens then.
