I understand you have held on your childrens' sake, however, they know a lot more than we think they do. They have got to have picked up on this entire sitch and it cannot be healthy for them at all.
I think if you let him go and deal w/ whatever it is he needs to deal w/, once you mourn, you will be in a much better place than you are now. You probably do not even realize how stressed out you are right now.
As for your neighbor, it sounds like she was taking care of her H b/c of physical illness, not mental illness.
I really think you need to stop fighting your H on this. You NEED to let him go. I really think if you don't, you are going to end up going around & around in the circles you have been in since 2005!!!!
He needs to figure things out for himself. You need to move on for yourself and your children. Your M is NOT healthy right now for you or your children. They have got to be seeing & hearing a lot more than you may think they are.
If he chooses to come back, please, please, make sure he is truly healed once & for all this time. I really think he needs A LOT of time out of the house & away from you & the kids.
