If that's the case, don't leave your wife wine or you'll end up with a retarded kid! Of course, from the sounds of things, you're probably not the daddy anyway, lol.
It sounds like your wife is bisexual or at least not that interested in you. I would take it offensive if my wife or girlfriend asked me to sleep somewhere else because her old friends were dropping by. I would refuse.
Instead, I would say and say that I insist. If she was getting it on with other women sexually, I would take that as a bad thing, not a good thing. BTW, the user above Pam R suggested a great idea, a spy camera.
See what she is doing, afterall, you do want to why she's asking you to leave for the night, don't you? Normally you shouldn't spy on your spouse, but this something completely different, this would be an exception.
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.
