Saying, "I don't deserve such a good friend, etc" isn't saying, "leave me alone", it's saying I don't know what, but it isn't a negative. Comments like, "I bet your glad to have a B like me out of your life", or whatever, may actually be fishing. You could have thrown her a bone (if you still actually want her), and said, "No, I'm not happy about that".
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
It is hard to fail, but it is worse never to have tried to succeed. Theodore Roosevelt
