Need advice, as this girl confuses 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? I am very confused as to what she wants out of this. Because she said NO when I had ASKED HER OUT
