What would you do in my place?

Hi, people. I haven't been on reddit for a long time but something happened yesterday that made me wanna share. Long story short, a year and a half ago my ex-fiance left me at the alter. Yeah, I thought it was a movie cliche too... we hadn't seen each other since. It was the biggest humiliation in my life. I was the laughing stock of that "wedding". He broke my heart. I left the state for some time after that and it's been a month since I came back. And yesterday I accidently met him at the mall with his new boyfriend and he said "hi how have you been" and I just exploded, I said "how dare you even ask me that, you humiliated me, you made a fool of me, broke my heart, my dreams and now you just ask me as if nothing happened instead of walking as far away from me as possible. Fuck you and fuck you too( to his boyfriend) , I wish you the worst things in life" and he said "i know you are angry I am sorry" and I just told him to fuck off and left. Can you believe this guy?
