Does this girl like me more then just a friend?

she hangs out with me and we have lots of fun. she even invited me to go to china with her. but sometimes a things get brought up about her hanging out with other guys and stuff. like a guy wanting to go see a childs movie and she was the only one willing to go with him. or her hanging out with her roomates friends and drinking coke instead of bear while playing a drinking game. she has never asked me oh what should i do if i like him or any advice like that but if somehow another guy gets brought up she will automatically reinforce the fact he is just a friend?
