I felt that way when this first all happened to me six months ago, I couldn't relax around my H at all, I was nervous and H noticed it also. He was also very mean to me and I took it and let him be mean to me, I broke down crying a lot and saying "why, why", but not more. That me is gone.
Now I'm at peace with myself and comfortable in my own skin. This has take awhile to happen, but just lately I've been experiencing this inner peace even when my H is around, which is a 180. I like this new me and don't want to lose this new me. You can do it too girlfriend!
