Hoping my marriage can be saved :(

[Cadet]

Welcome to the board.

It sounds like he is depressed.

He is asking for SPACE, give it to him.
Get out and GAL.
DETACH.
Believe none of what he say and half of what he does.
Have NO EXPECTATIONS.
Take care of yourself, breathe, eat, sleep, exercise.

You are on moderation right now on the forum.
SO post in small frequent posts until you get off of it.

Your H is giving you a GIFT.
THE GIFT OF TIME.

USE it wisely.
