Because many people don't realize what they have until they lose it! They love the attention and think that you'll be there forever to provide it. With some people it's a game and they don't like to see "the one that got away" and will probably try to see if you'll pay attention to them again.
This time they may even go out with you on a date or two, but DON'T! These types of people that know full well you like them and play with your head are not worth it! Happy to hear you have found someone else!
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.
