What does it mean when a guy says you make him blush?

Please don't say the literal meaning, haha...

This guy and I were flirting over text, and he was teasing me saying how awesome he was, and I said "It's true!" and he kept on saying on how I made him blush?

Did he blush because he thought what I said was cute?
