I totally agree with Rhuto.
When I read your last posting, crying and feeling guilty and conforming to your husband's unspoken wishes to give him space and so on... I thought, No, No.. you should not do that. You are in a way admitting guilt that he has not accused you of and giving in to him for something that he has not yet explained to you.
Keeping your own dignity, do everything you can possibly can to save this marriage; after that, as Rhuto said, it is his choice. OK? Please wipe those tears off - if he finally chooses to go, it will be his loss.
Hard as it sound, please smile
Blessings.
