Why is this happening to me?

Hmm... what a day it has been...I have no bad intention but do I have a bad karma? Today I was suppose to catch a movie with S. I met her at CCK Mrt control station at 2.30pm as agreed. But yes I was late for 5 minutes. We met and she seems so quiet. We board bus 188 to go Vivocity at 2.45pm. Inside the bus she told me her 2nd elder sister told her last minute that they need to go to her eldest sister's house at Bedok. I ask her what's her plan but she is not sure.

Cut the story short, we reach Vivocity and she changed her mind about watching the movie because she might be late to meet her 2nd and younger sister to go to her eldest sister's house. So we went to Banquet for a meal, after getting a place to sit...she told me she need to use the ladies. So while waiting for her I was thinking that something was wrong. Then I received an sms from S, saying that she is sorry and she needs to leave asap coz she do not want her sisters to think she never put family first.

The only think I don't understand was why can't she tell me in person and we could get home together since we came to Vivocity together. I do understand family always comes first. She msg me again saying she appreciates me for understanding. So I walk to the interchange to board the bus...while smsg her asking her how is she and did she take the mrt home, but no response. Few minutes later I sms her again asking if she is ok and yet no response. I called her like 3 times and still she never pick up my calls. I was so worried and I sms her again. I waited and just thought maybe she wanted to be left alone. I sms one her last time asking her to call me asap but so far no calls from her.

I need to confide in someone but I got no one as both my good friends are in Malaysia for different reasons. I just do not know what mistake have I done to be ignored like this. I am not like most guys who meet girls and their hands transform to an octopus. Only she herself knows what is actually in her mind and Allah knows. I just hope that she is alright because I can't get throughto her by phone, even called her house but no one pick up. I do not want to think any negative thoughts but if it happens....honestly I do not know what my reaction will be. I am sure there is an explaination because I, for once never think bad of people especially the ones I love.
