How to get over thoughts of your girlfriend with another man?

I recently was dumped by my gf, about 2 weeks ago after a 5 month relationship. I'm 90% sure she did so to move on to another man.





I'm beginning to accept moving on, but I have one problem. It drives me crazy to think of her with another man. How can I get these thoughts out of my head and make it not matter?How to get over thoughts of your girlfriend with another man?
