Let me add my own "redundant" view .... are we not putting way too much weight on a single letter. Should H not be able to express himself face to face with you Maria and tell you how badly he wants you to get back together? As I mentionned earlier today, there is no reason why you should rush into a decision.
Only you know if you have it in you to work at this...but the following quote from you speaks volumes to me: <<No, there is NOTHING=NOONE else that you "missed"... I wish there was.>> It is the last part, the wishing part that does not sound like it comes from someone who is ready to put on their workboots. Not saying I blame you for feeling this way...actually, I think he is lucky you are still accepting his letters.
