nate, i wouldn't say it's not possible to have only guy friends as close friends... for some girls, it's just that they get along more with guys than gals.
it's just the way they think.
nate, i'll just put it short, she likes you, she ensures you that that guy "C" is just a friend, it's up to you to trust her.
if you don't, let her know... if you consider this a potential relationship, then you guys need to talk about it, not just doubting and suspecting.
if you are assuming that she's fooling around and such, den it's still your choice if you want an explaination from her.
communication is the best way to solve the problem.
maybe it's low self-esteem, maybe she's just friendly, no harm to ask. JUST ASK her... in a nice way of cos.
