It is my job to care for him not hers damnit why can't he see that?
No, Serenity, right now it ISN'T your job. Whether it hurts like hell or not (and I know it does), he's told you by his recent actions and decisions that this most certainly is NOT your job right now.
You can't rescue him.
You can't control him.
You can't "fix" him.
This is HIS journey, and he needs to walk it, unenabled by you, naturally, but left to walk it nonetheless.
