Why would a girl block me from instagram?

[issac]

I always saw this girl saying shes bored so one day she put something saying want to text so i commented my number. She text me back and we text for about a week and i tried to set up a dated so we can hang out but she wanted to go with friends too and i said ok. I really wanted to meet her before we hung out so we decided to meet at her work during her break. It all went good i made her laugh smile and giggle and we set up the date and i gave her a hug and i left. When i got home i waited a while and i text her. She sent me a text saying it was her mother and her phone was taken away. Then i saw i was blocked from her instagram. My best friend told me she folliwed him the next day.I tried to text her and i kiked her no answer. What did i do wrong? Why did she block me? Idk what i did wrong i was just trying to be nice to her. Please help me im confused.
