I have felt like you are right now. I used to think that my H would never come home. He said he was happy and it was over. Just threw me and the kids away.
My H left his jewelry here too. What really bothered me that he left his wedding band here too. It was like we never even existed for him.
My H would disappear for weeks on end without contact and you know what????? It was good for him and good for me and the kids too. I had peace and quite and wasn't walking on eggshells all the time. It helped my H to miss us some too. It let my H be alone with the ow so he could see what she really was and for him to come to terms with his life and what he wanted. They need this time by themselves or sort through everything and to make it through this crisis.
Think of it as being good and not bad. Don't worry, a mothers kiss and hug will never get tiring. Give them lotts of them!!!!
