Were just friends....?

i have a male friend who i known for 9 years.we are real cool with each other. but people see more then that and i only see a friendship.i haves that swear up and down i like him.like yesterday my friend (this friend likes him)and i called him and we were talking and he was mostly talking to me.so he made a mistake a hung up and he called me back and we started talking i forgot all about my friend being on the other line (she hung up) so i asked if he wanted to call her back he said not really if you what to and then i said yea because i didn't want her to think anything was going on between us(they don't go together)but she still kinda likes him.but for some reason i think he likes me.what should i do?
