I find that people who are introspective are actually more apt to look at themselves as lacking in some way; not selfish...and they are trying to figure out what their part in the failure of the relationship was. I am very introspective and spend a lot of time thinking about a great many things...not just the person that I am having a relationship with at the moment. Just because a relationship is breaking down and one of the parties is spending a lot of time "in their head" doesn't mean that they are only looking at their own needs...but you will never know for sure unless you discuss it with the other person.
We can never know what another person is thinking unless they tell us. More.
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.
