Is this girl messin with me? Kinda long story. Sry.?

So I have been talking to this girl I like who is super cute :) but there's a small problem.. She is my ex girlfriends best friend... But when I was still with my girlfriend(this girl was after my ex) she tried to get me to cheat on her.. But I didn't... But I broke up with her a while ago... So I started talking to this girl..... but today I was texting her. And she was saying she was lonely. So I told her slwe should hang out together because I am lonely too. And she said yes excitedly. And then for some reason she started to tell me what type of girl she is. And I told her that it was a good thing that she told me what type of girl she is. And she said "why is that" so I told her because I wanted to get to know her more better. And I meant it as a good thing. But after I said that she kinda started acting weird and stopped txting me.... So my question is.. Is she jus messin wih me? Or did I do something wrong.
