I know this is more than a break up is it the discard that hurts the most?

For context I was on and off for 2 years & was discarded 3 months ago , 2nd month of no contact , monkey branched to another favorite person , I have try to explain to others that I’m over the person whoever not what they did to me , it’s more than a break up it’s the discard but I feel as they get tired of me bringing the same thing over and over how do I get over it in a way?
