Help with a girl?

[nick h]

So I met this girl online like 2 months ago, and we kind of started talking on and off for the first few weeks...but for the past 3 weeks we been talking to each other every day. We had like 4-5 dates.
She appears to like me(she even told me she did) and is interested in me...but today we were talking for a few minutes , and she said she had to go to across the border with her friend, and she would text me when she get back.
Anyway, a few hours later she texted me..and we started texting for two minutes..but then she suddenly stopped replying to my text. So , I didn't take much of it...but a couple of hours later, I went on facebook, and saw that she added a new guy friend around the same time she stopped talking to me. And I checked her online dating profile, and it said she was online...and her facebook also said she was online on her mobile.lol
Also, she texted me like 10 minutes ago( she last texted me 8 hours ago)...and she asked "are you awake?"...im thinking about just ignoring it...and just stop communicating with her..since it seems like she is just using/playing me when she doesn't have any other guys to talk to..

,So i was just wondering if I could get some of your guys opinion about her, and what I should do or if you had experience with this situation.
