Do I like him? Should I say yes?

Ok, so this guy I'm friends with just sent me the cuutest thing! In an email, he sent me a music video called I Remember You by Skid Row and then asked me out. It was really sweet, but just don't know if I like him that way. He's a little geeky, but sweet and smart. I've tried picturing us together, like him holding my hand or something, and honestly I would feel really uncomfortable doing that. But does that mean I do like him or I think we should just stay friends? What do you think?
