Is this a love triangle or maybe even a square?

my best friend katie is going out with my other friend nate (they've known each other longer), katie was the first person to know that i like nate, which she doesn't care. but now dennis (hates katie, she hates him) (nates friend), likes me. and he asked nate to call me to see if i would go out with him. but nate knows that i like him! and he is the one who asked me out for dennis! WHAT DO I DO!!!!
