I understand what your are saying. I have always let other people influence my decisions. It is a weakness that I have because I too am never confident in my choices. I'm working on that as well because I've learned that I am worth something and my opinion matters.
If my M does not survive, at least I know that I will be a stronger, wiser person. I am learning patience, self control, positive thinking, and most of all learning to like myself again. If I need to, I can be independent and that in its self is liberating. (not my heart's desire, I just know that I can).
