Hi Elke, you have had some really great words of wisdom given to you here. You are doing great and this is not a simple situation, nor is it easy.
I think it's interesting that you recognize yourself as changing, both inside as well as outwardly.
You know what your own intentions and motivations are toward other guys. From the other side of this, and in this case your husband's side, I think it is right for a spouse to be assured they are not in a relationship where they are feeling betrayed by their sig other and just sitting back and taking it (and this is clearly not what's happening, but, he might be a little extra sensitive as he works to discern this for himself).
So, perhaps there are some new challenges for both of you now. As you are discovering who you are, he is also realizing the need to discover again who he is. That is the beauty
and the difficulty of marriage... you are never acting in isolation without consequence to the other.
You gusy might want to look into some counseling if problems are arising, because this change that you are making can indeed be difficult for you both, even though the rewards are also/can be emmense. I would wager that your previous hesitency to finish with MF has something to do with this, too (and it's something similar for *a lot* of people). In the end, you are not doing anything wrong by deciding to lose the weight and then losing it. You
know that.
Also, it's not wrong to want to feel and be sexy -- we just need to think very carefully about how we choose to use that kind of compelling and sometimes irresistable power
(actually, I am being pretty serious, though). That is a natural and feminine quality. It's okay to be a woman, in all your glory !! What you are doing with these changes in your life is important enough to take a stand for... no matter what.
Keep your head up !
