Advice: sex and hypothetical situation

This guy that I’ve gotten close to and talk to everyday yesterday asked “hypothetically if we do do it, would you let me cum inside you?”

If trust him and we both know our sexual history so sex w/o a condom is ok for both of us and I am on the pill and take it religiously so I say “yes”

He later replies “too bad at never going to happen”

Was he joking around since it’s a hypothetical, I can’t tell if he was being serious or if this is a sign we are or are not going to take this relationship to the next step.

Idk what to think. I feel like I’m thinking way too much into it.

Advice please?
