When He Chose the Intern

When he came back from the battlefield in Afghanistan, he was haunted by nightmares and dared not sleep all night. I put aside the therapeutic boundaries, spent five years accompanying him through every panic attack, and even pulled him back from the edge of self-destruction. But he turned around and used my money to support an intern who looked like my younger self, saying I was "too stale and always treated him like a patient". I used to be his salvation, but now how should I settle this betrayal?
