Re: unhappy marriage for 23 years
You can always keep your children and your grandchildren as close as you like, and without the duties that go with an un-appreciated wife, you will likely have more time and energy to devote to the kids after all.
We have to learn to put others first, and we can equally learn how to put ourselves first. To live your entire life never knowing what the second one is like, is a great loss.
Who knows, when you husband realizes what life may be like without you, he may kick it back into gear and start trying again. I encourage you to express your feelings, and start taking some action to either force a reaction or give you the answer you need.
