123Snap, Hey, just wanted to reiterate what brokenhearted said. You absolutely must give him as much space and time right now. Do your best to focus on you and your kids and not your M.
I am having to do a lot of the same. My H has left me 3 times over the past year and a half and we are now on our fourth try at piecing. Each time right before he left me, I could see and sense his depression building. It would scare the heck out of me, and send me into a depression myself. It was very hard during those times to just act as if.
In retrospect, I kindof wish that during those times I was not around him so much. It would only make matters worse. Then he would leave again. I guess that I am suggesting to give him distance and stay busy so that he doesnt have to feel like he is pressured. He sounds very overwhelmed right now, very confused, and he will need some alone time to sort this out.
I know how you feel. Your H comes back to you and says he wants to work on things again, but then after a short period of time their efforts seem to fade. They start to pull away, and the whole process starts over. It is very frustrating. Many walk away spouses come and go several times, sometimes I think they come back to the M before they are really healed. So there depression starts and they start to feel like it is becuase they are married to you that causes it. When in reality, they would most likely be depressed with or without the Spouse.
Good luck with everything, and try to back down a bit like you were saying. Keep coming back here to vent. You really do have a lot of positives to be greatful for, and you cant read the future so dont assume anything. Take Care, TIPPER
