She hurt me, why is she playing games with me?

I asked the chick i liked quite a few days back to which she said "No at the moment". i decided to move on and stay aloof. B Today accidentally i was typing "totally in love with you" to my sister (as it was her wedding) i typed to the chic i liked. to which she replied "batting eyelashes". But i cleared the air that "glad you realised it was a joke" she replied "Aah *phew*". i then said "it was for someone else but got to a wrong window" she asked me "so you wrote love you in a wrong window?" i said yes. "She just replied "AAH :)" I kind of love her. but this thing was actually meant for my sister(only as a part of a continuing convo. Also she just wrote on her BBM "Yes, and the task is to play it uber nonchalant(careless,ignorant) & cool. #Newguytricks" Later, I told her that although accidentally, I think its good that the love messaged reached her and that I mean it now and this time its meant for you and you alone. She replied saying *blushing* She starts addressing me "baby" suddenly again. However, for a couple of days she hasnt replied to any texts i sent, may be because she was out of town. But even today she didnt reply? Yesterday, I had asked her to meet, she replied that “I wouldn’t say no, but I get done at 11pm, so how do we do this”. We eventually met and I dropped her back home. She also got a friend along. I ended up having more fun with her friend than with the chick I like. The chick I like hardly talked or was always on the phone. Just before dropping home she says, “My friends coming home, you come home too, otherwise I’ll feel bad that I used you as a driver.” I felt really hurt. I was below the building dropping her and I said that I’ll go home all she said was “Okay your call, because You have work to do too and I cannot spend time with you per se” and I left. Later I just messaged saying happy journey, she replies saying “Thank you baby”. But when we move forward in the conversation she is very cold and dry. Also before boarding her flight I said I will miss you. She replied saying “Why will you miss me? I am going only for 4 days. See ya once I am back” Suddenly she'll address me as baby as a one off and then be dry and cold. Did she not like the fact that I was having better time talking to her friend than her and hence she insulted me that way or does she just doesn’t give a **** about me. I am very confused as to what she wants out of this. Because she said NO when I had ASKED HER OUT
