Well, I've been chatting up this girl for almost a month and a half now, she lives in a different city so we saw each other once. I went to her city and we had coffee, everything went well. She always texts me, calls me, sends me clingy texts, once I had a picture with some girl friends of mine and she said who are they I want to kill them, jokingly of course. I thought she liked me, she kept facetiming me, if I didn't respond on Instagram, she would keep sending directs until I did. Which is why I don't get what happened. She told me 3 days ago that she will come to my city for a night out with her friends and that I should go out with them too, I agreed. Then yesterday around 6 pm I told her to text me when she comes here, she didn't respond. I thought ok she probably doesn't have internet or didn't see her phone. Fast forward 6 hours later, I go to the night club and surprise surprise she's there. I approached her and asked why didn't she tell me that she will come, and she said that she didn't have internet, acting all bitchy and ignoring me, I got really nervous and went to my friends. I was a bit drunk so half an hour later I again went to her and started talking and she completely ignored me and moved to the other side where her friend was. That's when I really had it and I texted her that I will not allow her to treat me like that, she again didn't respond until today at 12 pm. She said that she knows she's guilty and nothing she can say will change that, but also said that her friends didn't want me there that's why she didn't tell me, she said she couldn't say that to me. But I know she's lying, if her friends didn't want me there why then would she act like that, completely ignoring me and giving me that smirking smile like she's above me. It was a complete change to her behavior. I seriously don't know what happened, as there is no point in asking her, she will just tell me the same.

Anyone ever had similar experience? Can you give me some advice about what should I do next?thanks.
