Am I wrong for asking a girl to a date that went with me to the cinema for free?

Am I wrong for asking a girl to a date that went with me to the cinema for free?<br><br>I invited her to the cinema a while back and she said yes, went to the cinema and had a great time, the problem is that she invited her best friend that wasn’t going to come, had no money for her ticket and her friend wanted to stay home alone, so I decided to invite the friend for free, the problem is my crush/cinema date is acting weird, ashamed, don’t want to go on a date again and I don’t know what to do, I invited her to the cinema last week and she said it’s weird cause I invited her and her friend for free on my own expense, I don’t know what to do or what to tell her, should I just give her money back when she was the one that I invited in the first place and I gave money for her friend?
