Does this girl like me?

We have been talking for a month. By text and fb. Before she talked to me for the first time, I noticed her staring at me and stuff. But not complete staring. Anyway we talk lots, she calls me bff. And says me '<3' after thanks or sorry or hey and stuff. She has incited me to parties and tells me to come see her at school. Though we haven't talked face-to-face much. Some concerns though - she just got over a break up , but hates the guy. And is known as a flirt and mean. However, she is super nice to me. Think she likes me ?
