I do relate to what you're saying, about the boredom and frustration, the not having the energy to expend on cherishing yourself, and the unsatisfactoriness of the substitute friends. And my life's not half as tough as your's is right now!
I agree that the lynchpin of the problem is your relationship with your dh. It may be that it's financially necessary to work so many hours (both of you), but it's extremely tough on your relationship, and if that's already rocky then it's even harder.
But if your dh won't go to counselling with you, it may yet be worth you going alone. Yes, the can of worms that would probably be opened up for you would be distressing, but then it would be important for you to conintue the counselling sot hat you coulld capture all the worms and deal with them. You cannot change a man, but you can change your reaction to him, and your behaviour around him, as well as your feelings about yourself, and all that can help. At the very least you can feel that you are doing something for yourself, that you give yourself value.
