I'm addicted to his laughter.
Why are you addicted to his laughter?
It makes me feel euphoric.
It's great to have someone that can bring you such happiness. I hope you can hold on to him.
Yeah, but I still want to make him feel like shit for breaking my heart.
That sounds hard. You should talk to him about how his actions impacted you instead of trying to make him feel bad. In the long run, if he understands his behavior it can be more helpful than punishing him.
