I think you need to speak to you husband about this and get him to have a word with them. Alternatively, you could speak to them yourself. I get the feeling that they are just protective over their son and are a bit scared of losing him even though your intentions are not like that.
I just think you need to stand up for yourself and let your in laws know what your good enough for their son and will not be walked over. Alternatively, you and your fiance could move out and look for a place of your own.
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.
