Have you ever dated or married someone a lot smarter than you?

My husband took an IQ test in high school and scored a 138 and one before college and scored a 142 to see if he could get in college for free. I don't have a problem with him being smart, but I feel so stupid! I don't have a deploma or a GED. I do some things I'm good at, the things Im best at. And he does it, and in less than an hour he is better than me. I know I must sound immature, but geez. I can't even win an argument because he always makes me feel little by explaining every detail, and telling me "how i must feel".
