How bad did I screw up?

I (31m) went on a 5th date with this girl (34f). Everything was going great as usual. We were eating then she suggested going to the lake or watch a movie at her sister's house (where she lives right now).

I asked if she thought her sister think it would be ok for me to come over. She then changed her mind because she didn't want her sister to think we are boyfriend/girlfriend. In a joking tone, I said "ok how about 2 more dates and we can be boyfriend/girlfriend".

I can't remember all of it but she was questioning why date 7 then I said "ok maybe date 9". Again I thought I was making it obvious that I was joking. Then I said "ugh, you are so difficult". She became cold when I said that. Head facing away, arms crossed in the truck.

She said she didn't feel good (English isn't her first language). I knew what upset her and apologized from my heart. She said she wanted to go home and search her feelings. So I brought her home. I asked if I could get out with her and she agreed.

She gave me a hug and I apologized once again. I asked for a second hug and we hugged a little longer. She offered me leftover Halloween candy and I accepted. I asked if I could still text her and she still said yes (I'm not sure if it was a real yes though). I texted her I made it home but left me on read.

She is leaving for a week trip on Monday. Should I wait until she gets back? Judging from how she reacted at her house how bad do you think I screwed up?

I've lost sleep over this one. Thank you for your time reading this.
