I'll bet you have more in common than you think you do. My W always says the same thing "just the kids" yet when I put my mind to it I can come up with more things in common than fingers to count them on. Even small stuff is good stuff, I'll bet you even watch TV once in a while See what you can come up with: walks, eating out, church, scrabble, watching the news, the color red, shopping for shoes (oops, what am I saying!) but you get the idea. Sometimes an A creates a mindset where a great deal of time has been spent wiping the memory clean of any commonalities etc in order to legitimize the A. It might take work to bring that stuff back. Think about why you married him. There must have been oodles of good reasons then, are any of those still relevant today? I'll bet there are still a few. Is he the prize he was then, most likely not but, if you choose to stay, you start with what you got!
