I really don't think you should be trying to get over him! Yous seem perfect together, and its great that his family like you and you feel comfortable You should speak to him about the whole no contact, other than face to face I suggest though.
Maybe hes just that kind of person who is not very good at communication. Leave it alone for a while and see if he says anything. Then if he doesn't try to slyly find out if he wants more.
If the sneaky approach doesn't work, make sure to let him know you love your friendship but are a little confused over what he wants from you. See whhat he answers, good luck!
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.
