Is she just a slut or something?

Anonymous
I have been texting this girl I like for over a month everyday. I told her I liked her when we first started talking like a Month ago when she had a boyfriend, but know they broke up and she stopped texting and talking to me, and know it's a week later and she has a different boyfriend and she still hasn't talked to me since. I know she liked me before her brake up by the way she said stuff and the stuff she said l, but know she stopped and its like I don't even know her now. When ever I pass her in the hallway she always smiles at me and says hi I don't really know what that means. I don't know what to do, should I text her and ask what's going on?
