<human>: Can you condense the text into three sentences or less?

Okay so I just started dating this new guy. I really like him, but I'm worried our different intelligence levels will prove us incompatible. I consider myself slightly above average intelligence wise, but he is crazy smart. He's a college graduate and works as a computer engineer, while I'm still in school pursuing a degree in English. He's always talking about these concepts in physics or philosophy or politics that go way over my head. Sometimes in conversations I literally have no idea what he is talking about. 

Not trying to be arrogant or anything, but I am very conventionally attractive. He is less so. It's kind of a "nerd dating a hot girl" situation. I'm worried that he's only with me for my looks. He's made it clear that he likes me a lot, but I don't know if it's for my looks or personality. I think a more intelligent person might fulfill his needs better. 

I really really like him, but I'm worried that he won't be fulfilled intellectually and will eventually get bored of me. That combined with the age difference (he is more mature than me) has me worried that this relationship won't work out. I really like this guy, but I don't want to set myself up for heartbreak. Does it sound like by doubts are legitimate? How do you date someone that is a lot smarter than you?
<bot>: New boyfriend is a lot smarter than me, makes me feel inferior, not sure if it's going to work out.
