My aunt introduced me to a boy. His family condition is very good, but mine is very average. My parents are honest and don't talk much.

This is no small matter. You should choose a time, tell him your family background directly, and let him decide whether to continue. You can't hide. He wants to find a good condition, and you get hurt. Oh, even if you finally separate, will you feel at ease? Yours is yours, not yours.

Good luck!
