I think you should STOP editing pictures of your ex-girlfriend.
My ex-wife was once screwing me over on totally BS stuff. I had to get a lawyer and build a ginormous case just to prove innocence. A few days before court, we backed off. I sooooo wanted to go after her for making up crap. My lawyer told me that I should just cut my losses and move on. If I engage her in a counter-litigation, it will only mean that it will take me longer to move on from her, and she will still be in my head, despite her being gone forever. I decided to take that advice and just cut my losses and keep it moving.
I am now extremely happy in life, and couldn't care less about her. The point being, you should not be spending your time doing anything related to her. Try to pick up and move on. Life is full of adventures!
