Grow up for starters, why would you intentionally hurt someone you are claiming to love. If this is not so then you did it to hurt her for whatever sick reason. Now she has left you.
Did you learn your lesson dear.....moving right along. If she is insecure what makes you think she will feel secure being with you after what you've done, and you had the nerve to tell her. Something is really wrong with you, get it together before you end up by yourself!
Forgive yourself my good man. Forgive yourself. You did the right thing when you told her the truth.
Now you have to do the right thing for yourself and 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.
