Hey, first of all excuse my English. I am 17 and go to school with this girl. We are fwb currently. This morning she hits me up with 'I had a disgusting dream that I made out with [friend from class that was kinda hitting on her]'. I told her that that is an insult to me, then she said it's just a dream and won't happen ever.
Me: 'it better not'
Her: 'and what if it did happen?'
Me: 'what do you think?'
Her: 'I asked you'
Me: 'I get it but what do you think?'
Her: 'hey I asked first. We will talk when we see each other'

How did I do? I want to say that idgaf that she asked first but don't want to come off as an asshole. Should I just wait until we meet? And what should be my next steps when we see each other and bring up the subject? I want to tell her that I would just never talk to her but not sure if that's too harsh. Thanks guys
