I was in the same situation. It seems like he's trying to make you hurt the way you made him hurt. If you have been after him and have said you are "sorry" it's time that you leave him alone.
He needs time to think without you. It it was mean for the two of you to be together you will. Take this time to work on more of your issues and what you feel are your weak points in your relationships.
You need to save what is left of your pride and give up. He's never going to take you back. He's just toying with you so he can vent his anger at you.
It doesn't matter what you did to him in the past. Earning someone's forgiveness should not require taking abuse from them. There is nothing healthy about this situation, move on.
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.
