He left you.

You tried reasoning with him, telling him that he was joining the wrong side.

But he didn't listen.

So, quick backtrack. You and Luke had been dating for a while now, and you knew all about how Hermes left him and his mom. You were always kind and understanding with him, the best loved he could ask for.

So when he left... It hit you harder than anyone else.

You couldn't go with him. You just couldn't bring yourself to do it.
