If you've talked to him and he still does nothing, just remove yourself from the situation. When he comes over, go for a walk or a drive and in time his friend will ask why you keep leaving, then perhaps your husband will have that talk with him. Being treated badly is still a form of abuse and he should be protecting you from it.
When I say talk, I mean a heart to heart talk, face to face and get the air cleared. Tell him how it makes you feel!
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.
