I felt in my gut that something like this would happen, one day, some day. I just hoped it wouldn't.

I asked DH to take our kids with him when he went to drop SKids back on Sun, so that I can finish up some stuff at home. He was dropping them back at BM's parents because they were celebrating some birthdays there. I usually always go with him.

He left DD at his own parents place and took DS with him because he was sleeping in the car.

Usually, when I am with him for the drop backs, he doesn't come out of the car and if he does it's to hug Skids and say goodbye but not go in to house, because we had this issue in the beginning and I have asked him many times not to.

On Sun, from what I can figure (because he lied to me and said he didn't go in) is that he came out and spoke to the grandparents at the doorstep, but he eventually went in and perhaps even stayed a while and drank (alcohol) at the house. He then went to his parent's house and hung out and drank some more and came home almost drunk, with our 2 kids in the car, ate food (he had barely eaten all day) and passed out.

DS(who is only 3) told me he went inside and met uncles and aunties and hugged the Skid's baby sister (BM's baby).

I am furious. I feel so betrayed. I feel like I'm right back to the beginning of our marriage when he used to go inside when dropping back the kids and spend hours talking and drinking with BM. I feel like I cannot trust him again.

WE have spoken about this scenario so many times and I have always asked him to not go in - if the situation came up, he had said he would not.

I thought having the kids would at least be a deterrent to him going in the house too, and I simply cannot begin to imagine what happened for our son to be out of his carseat and in those people's house!!! DH has been gone on a business trip and so, we have not talked and he has not even tried to fully explain himself, neither has he tried to apologise (and he probably never will, not that it matters anyway).

If I had gone in the car, he would not have gone in. But trust is when your SPOUSE will behave exactly the same way as they would if you were with them, right? Trusting when you know it's not true is pure stupidity.

I honestly feel as if my marriage could now be over... I feel like I can live in the same house as him, but I will never 100% trust him again.
I will be gone on vacation in the summer (with our kids) and he will be here alone. I feel like he will be falling right back into BM's family when I am gone, given this precedent he has now set.

I honestly don't know what I'm going to do...
