It has occurred to me that it would actually be easier to start over with someone new than it would be to rebuild our MR, but I am not afraid of the hard work.
This is exactly what I think my H is going through, who is moving out today. Although I believe he IS afraid of the hard work to repair/rebuild our marriage as he doesn't want to face his demons. I fear he will find it easier to feel good with a series of other women than do the work to feel good about himself for himself. But, I remind myself that that is his journey to take. Not mine.
