Ok so I started talking to a random girl on facebook (I don't know her in real life). I've spoken to her 3 times and managed to get her number. She always replies but usually gives me fairly short to average length answers. She uses a lot of smileys and we flirt a bit. She also started putting x's at the end of her messages/texts. However she doesn't ask any questions and I have to start the conversation. Is she interested or not?
