Is 4 months too soon?

[scratchinghead]

Im new to this and Im very confused..
After many years of my H being critical, judgemental and a bully I finally plucked up the courage and left him. We were married 30 years.
He begged me to reconsider saying he would change, that he would be kind to his DC's, that we were his life.
But I stuck to what I felt despite it being really hard as he was using DC's to get to me.
I knew after about 6 weeks of all this he had found someone else and one of our DC's tells me they are now house hunting together.
I am totally gobsmacked at this, surely 4 months, which is all it has been, is way too soon to move in with a new partner and just expect DC's to accept this and for her to almost step into my shoes?
Fair enough if he wants to move on, but move in?
Or maybe that was why he was so horrible to his family, because she was always there? But if so why not leave us to live with her before?
As I said, confused..

Because their posts were better reasoned and weren't trying to have a pop at the OP?

Because there's nothing in their posts that betrays a deep and irrational fear and dislike of women?

I think it fits very well with what you already know about him. Some men just need a victim to belittle and put down, that's the only way they can feel adequate themselves. Not your problem any more, thankfully, though your poor DCs
