I have just read your posts and you are an incredible lady. i, like you have been with my h for 10 years, married for 6. Husband left end of Jan 2009, found out about other woman Feb 2009. We have been separated for 6 months.
I understand exactly where you are coming from when you say that you don't want to move on to a new life or new R but you want to concentrate on yourself and not focus all the time on your H and the M. I am going through these thoughts daily!
I think that the move that you have made is a brave one but in a way will define and clarify your situation with your husband. My H has said very similar things in some cases.
I just wanted to lend my vote of confidence and support to you and to say that you are doing a great job. the dips in the roller coaster will be there of course too.
