wow... she did bother to reply, which means that she is thinking about things. when i think back to when i was acting like your STBXW, i wrote a letter very much in line with that one.
honey, you have really got to keep down this path of acting "as if" you are fine to have a life without her. eventually, you will convince yourself that this is true - my H did. don't worry about what caused her to reply, it's probably a manifestation of all of the detatchment work you are doing. your letter did, however, obviously have some effect on her.
