Her non-answer really ticked ME off, so it must have really gotten under your skin. "We'll see how I feel?" Talk about conditional love. You're not asking for her to marry you for goodness sake. Just to let you know that you were a part of her life for a period and during that period, she saw positive changes in you. You are a good man whether or not she writes the letter (which obviously says way more about her than it does about you) and I hope you don't base your esteem on whether/if she writes something.

Hope I'm not offending anyone. I don't post often b/c I usually wind up killing a thread. I have that way with people
