The results
Mostly A’s — You asked him straight. You asked what he wants rather than what you are, which is the much harder question to dodge. Whatever he said, believe the version of it that matches what he’s actually done since.
Mostly B’s — Auditioning for the title. You’re doing the job hoping for the promotion, and nobody gets promoted for unpaid work. Ask what’s changed since month one. If the honest answer is nothing, that’s your answer.
Mostly C’s — Scared of the answer. If one plain question could end this, you already know what it is. Fear of the answer is the answer, and it is far cheaper to find out now than it will be in six months.
Mostly D’s — Casual first, so it can’t hurt. You got there first so it couldn’t hurt. Worth checking whether you enjoy his company, or just the relief when he replies. Only one of those is actually about him.
