Answer I would not call him at all. He made it clear. He must know how to get a hold of you.
The ball is in his court. I would get out and enjoy myself. See whats out there.
Don't wait around for him to call. You will feel worse and look so desperate if he calls. He knows he can have you anytime.
You are not a challenge. Don't play games but do not be at his disposal. Once he sees you moving on and meeting new people he may come back.
If not, you havent lost anything except gained a new life.
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.
