Has your dh checked out of family life.
You seem to lead such separate lives. What does he do now for you and the children.
Not about what he gives in monetary terms but what he gives willingly of his time and thinking about what you would enjoy doing even if it is just going for a walk in a nice area/park etc and taking a picnic or just spending time with you all doing something you all enjoy.
There are single parents and single parents who are married.
Being a single parent beats the latter hands down
Personally I suspect that you live in a house that you think you could never afford and that is why you stay.
My only warning is that it is an illusion.
Look at what price you pay to live in such a lovely house.
He at the moment holds all the cards and when he is fed up with you he will toss you aside and move in a younger model who will insist they have their name put on the deeds and then your share goes down
It happened to a friend of my mothers years ago who actually worked f/t and had contributed to the household. She ended up on the settee and he was upstairs sharing her bed with his new gf who he had moved in and given half the house to.
She ended walking away with very little as it got too much and she moved out and as it was no longer the marital home (he waited till their youngest was 16 and in work) and the house with her ex and his new gf on the deeds meant he ended up having to pay her very little compared to 1/2 the house worth.
Just what she had paid in over the years.
Be warned. This lady never thought her dh would ever contemplate such a thing and it came as a shock to her how little he thought of her.
Everyone else looking in, it come as no surprise
