Of course you'll still have a love for an ex but what you need to do is get over or move on from the idea of a relationship and just keep on doing your usual thing.
I still have strong feelings for my friend. Everytime she was close to me I would be overpowered by her beauty. Its been more than four years.
I know she's forgotten the guy that loved her but never kissed her... You could try to go back to her. Take a chance & don't be mad if she has found someone already.
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.
