I met her at a bar, went out with her for bowling and she asked to bring her friend I was ok with that because we didn't know each other much. We had a game laugh, flirted a bit with her.

There is an event that she messaged me she wanted to go I told her sure I'm free "X" day and she want to bring a friend again. I said I would rather be only the two of us but if you want to bring her that's alright. She still told her friend so she probably doesn't want this to be a date and is treating me like a friend. What should I do?
