In the Spirit of Honore' Daumier
Move on.
My advice is to find the hottest girl you can, preferably younger than you ex. If you know things your ex hates about herself, try to find those features she wishes she had in the new girlfriend. Plaster pics of you together on social media for her to see but with little detail.
Above all things, always make her think she doesn't matter any more.
Sounds like you been there and done that...
