She (31F) invited me (31M) to a date and dumped me. What have I done wrong? Shou

I met this girl in a company (friend of a friend) and we got a lot of fun, she was next to me all the time, there was a lot of chemistry and we slipped away from the others and went to another bar, we danced, kissed, got a lot of fun and laughs. After that we went for a dinner, both ware very hungry, then she asked me to go with her to her place. I did. In the taxi she asked me just to leave her at her place. I agreed of course, she gave me her phone number and asked me very insistently to call her the next day. I kissed her goodbye, and went away. I was not really hopeful about all this:people on parties drink. Anyway I was busy and was thinking to call her in the afternoon. But she actually called me first (I was going to a business meeting) and we talked till I was on my appointment, she invited me to a date, she was very cute and charming on the phone. After my business meeting I went with my business partner (fine looking woman) to a store just for few mins AND in the same time my date entered the store by accident. She was really quick to leave after a brief chat, she was upset to see me with the other woman. Late that night she called me again and we talked for 40 minutes about the date for tomorrow and few times she tried to get to know who the lady was. So I calmed her that she is just a business partner. Anyway, we agreed that next day we will call each other to set the place. After work I called her but no answer. I got a message: Still at work, she called me hours later (after 20 PM) and told me she will have dinner and we may go for a drink or I’m going to join her. She was far away and I told her that will go the bar and wait her there. She agreed and told me that she will be there in 30 mins.1 hour passed. So I rung her phone, nothing, rung again – nothing. After 3 hours I got a text: was with my parents. I rung her and she told me just: was with my patents. So I asked why she called me if she was not available. She just hang up. Rung her last time. Nothing. This was yesterday. I did not called or texted since.
