Do you think its wrong that my friend is doing this...?!?!?

Ok. So I like this guy. Lets say his name is Bob. (not his real name.) So I told my friend that I like Bob and shes like oh really, thats cool. Ok, before I told her I like him she payed no attention to him what so ever. But ever since I told her I like him, shes been talking to him, and everything with him. I mean, where the heck did that come from? And then to top it off, she tells me she likes him too. Whoa! First, I tell her I like a guy and then, when she was not even talking to him before I told her, she starts acting like they are a couple and tells me she likes him too. I just think this whole thing shes doing is wrong. Tell me your opinions and if you agree with me. Thanks. Advice appreciated mucho:)
