Just shocked

Around 2 days ago, one of my friends informed me something about my ex. Turns out they got with the person they were cheating on me with. I was hurt sure, but to add salt to the wound, they’ve been dating for a month. But, we’ve been broken up with for a month. Turns out the moment we broke up, they went to the new person. And if I’m being honest, idk how to feel. The cheating I was fine with, what’s done is done. But the fact that as soon as we ended, they got with the person they cheated on me with? Someone they just met? Crazy…. Anyways, that’s all I wanted to share. Happy new years ^_^
