Hey Gingersnap- Thanks for stopping by my thread. I don't have the answers either. My H is similar to yours in that he has moved out and there is no OW.
We are "dating", we ML, he calls me sexy, he ocassionally says ILYs; he says he loves me, doesn't regret our relationship; is paying the majority of the bills ... EXCEPT-he doesn't know whether or not he wants the marriage and he doesn't seem to want to "do" anything different to save it.
The marriage to my H is more "stable and loving" that a lot of marriages out there. We respect each other, love each other and have a good time together. We are best friends. We're attracted to each other. But, he wants more excitement. I think he thinks the "grass is greener" out there. He tells me "something" is missing.
So, as far as what is in your H's head--I really couldn't tell you and maybe your H couldn't tell you, either.
Have you asked him?
