Jeff is so right. None of this was your fault. Your kids know that. You are going to have good days and bad. That is to be expected. Hang in there.
As for the attraction to us. Right now they probably aren't but that is because they are wrapped up in something they have no idea how to get out of. The feelings are buried so deep inside of them. My H used to tell me in the midst of all of this that he had no attraction to me what so ever. I was thinking to myself that it was there just a couple of months prior, what happened? The ow and MLC is what happened!
I know the loneliness. I had some really hard times too. I wanted to call and try to talk some sense into him. All it would do is make him angry and pull farther away from me. The less contact I had with him the better it was for both of us. He seemed to miss us at times and even sometimes he would say that too.
