Navigating Pain and Dua After Being Hurt

Salam. I recently experienced a deep betrayal from someone close. The hurt is so intense that for the past three days, I haven't been able to eat properly. The emotional pain feels physical, with constant tears and a real ache in my chest. In this state, I've found myself making dua, asking Allah that this person experiences a similar pain so they understand what they've done. Part of me worries this is wrong, but the words just keep coming out. At the same time, a quieter thought in the back of my mind wonders if I should instead pray for their guidance (hidayah) to become a better person. But I don't end up making *that* dua. I'm not sure if that's me holding on to my self-respect or if it's a lack of trust in Allah's ultimate wisdom and justice. I'm really struggling with these feelings. Any advice or perspective would be appreciated. JazakAllah khair for listening.
