I seem to be at the same point you are. Although there is NOOOOO indication that my H would ever want to come back, I am not sure that I would want him back.
I too sacraficed so much of myself that it is frightening. I did it out of love. I did it to support my H's career and his needs and those of our family. Somewhere along the way I lost myself.
I have very good friends of both me and my H that say he was this way for so long. I didn't see it. In hindsight I can somewhat. But he was also loving and adoring, to a point.
Anyway, I wanted to stop by and say I'm glad you are doing things to make YOU happy. Embrace that. Be YOU and enjoy the heck out of it. Whatever the future holds will be beautiful if you are true to yourself.
