Don't waste yours and his time.
The only reason you're even remotely entertaining this idea is because he said he likes you.
Thats hardly reason enough to consider taking things further when you have stated numerous times you feel nothing towards him.
Now, if you don't know him, of course no one expects you to know if you love him or not. But going by your posts, you have zero attraction towards him...so why are you even entertaining this idea?
