Your example is NOT accurate. Not wanting to be married to someone does not equal something being "wrong" with the person you're married to--just that it may be the wrong match for you.
Heck, I stayed married for over thirteen years to the guy, and it was only because I felt so guilty leaving him that I stayed that long. So if there was something wrong, it was with me, not him. His present wife is happy as a clam with him--they are now married about thirteen years, and seem to be very happy together. I stay with them when I go to visit my kids.
Learn to accept being wrong once in awhile. It build character.
