No, you don't have to "move on". That's a choice that you can make, though. Like Jeff always tells me...Life is full of decisions and choices......it's the path you choose that matters.
Well, wait....maybe you didn't mean "move on" like I think you did...as long as "move on" doesn't entail meeting other women while you are married, I agree.....because in that sense you are saying to GAL and that is good.
See the movie. If not this weekend, then next week. And, if you want to drive the point home with your ss he should go with you. He really needs to see the other side. Your wife has shown him only one.
