Yeah, let him know that's a sensitive subject with you. I'm guessing he was saying it in a joking tone.
I have the opposite problem. People tell me I'm smart often (probably because of the glasses), and so they are typically less apt to explain things to me. I have to make sure to let people know that I don't know what they're talking about to get the whole story.
Intelligence is truly in the eye of the beholder much like beauty. The only thing that really makes someone unintelligent is an unwillingness to learn and change.
You may have had to work harder than most in school but you are by no means a dummy because you chose to learn.

Tell him you're hurt by his remarks.
It's unfair to say 'i can't forgive him' if he didn't know and you didn't tell him.
