Firstly, you can't just "think" he's having an affair with a coworker, but know for sure. Are you the jealous type? Is there good reason for you to feel the way you do?
If so, how do you know for sure he is cheating? In the workplace many men and women have to work together and even over-time, but that doesn't mean they are having an affair If he has admitted to it, or you've caught both of them together then give him an ultimatum .... "Me or her! " If he doesn't decide, then tell him to stop seeing her or pack his bags."
Never sit by and allow anyone to do this to you. If he doesn't smarten up then it's time to kick him out. Do it smart ... see a lawyer!
Good luck Marcy.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
