Sometimes people stay together for 10+years even when it was the worst relationship they've ever been in...just ask my W
But seriously, when the WASs walk away from so much for someone else (lust usually) they do feel they're stuck. What are they going to say 'oh, I made the biggest mistake of my life, this is horrible I'm done here...' while that would be the right think to do but they keep trying to sell to themselves that this was a good idea and it'll work, maybe things will get better with time, maybe things will be better if I marry her etc. But it's like quick sand and ultimately one or the other will do this because they're who they are. If they can walk away from their wives and families so easily what's stopping them from doing it again.
