She expects you to run errands for her, on your lunch hour/break?!

I've seen some couples where the man decided to wait until the kids were grown and out of the house before splitting.

I've seen relationships dissolve and turn into better parenting situations.

I've seen relationships, where both partners go to individual counseling for the sake of their relationship, and that works.

For the sake of the kids...hmmmm, tough one.

Are you currently in therapy, yourself?

I've often said, how can one leave, if they don't know how to stay?
And I've often heard, I will only leave, if I can no longer stay.

It's not an overnight decision. Does your wife, realize your level of dissatisfaction within your marriage? And if so, what is she going to do, to meet you halfway?
