HELP! 2 guys at work!?

i reeeeeallly don't know how this happened. i'm new and i work with these two guys. the first has been tottally awsome in helping me adjust and he's totally cool, and i've been looking to make some close new friends.... so i asked him in a very un-flirty way...."nate, dude i need some one to come to this concert with me in NY, do you want to come?" NOW he'll ask if i can do things after work and gives me sweet compliments. he's definitly moving in. i'll say "yeah...dude you wanna get some drinks cool" when he asks me to go out, he insists on paying and i wish he wouldn't. then this other guy was at first kind of rude. he was leaving work one day and i accidently said "awww your leave" like i was upset or somthing (i DONT know why), now HE keeps making jokes that i owe him dinner and he's become REALLY sweet and helpfull all the sudden. he asked me on mysapce when we're going too go out..i havn't answered yet. i'm afraid i'm headed for trouble.
