Search Results: start talking to this guy on facebook

So, I recently met this girl. She's very collected, and has her shit together, for the most part.
We met at my job and we started talking for a bit and realized that we have the same sense of humor (sarcastic dad-jokey type of humor) and we exchanged numbers. We talked almost constantly for about two weeks before we decided to meet up again (our schedules didn't match up until then).
When we met up, we got food and sat at the local park. She was wearing a crop top with leggings. This is important later.
Whilst we were sitting there, I asked her if she was cold (it was fairly chilly and windy, and again, crop top and leggings), and she told me she was fine. However, I could see her shivering, so I offered my sweatshirt. She politely declined.
We ended up leaving shortly after because some drunk dudes showed up and started hitting on us. Both of us.
Fast forward to yesterday (about a week after the last time) and we met up again. This time, we met at her place. When I got there, she answered the door in lingerie. I jokingly asked what the occasion was, and she said, and I quote...
"I'm waiting for the other two guys to get here. Did you bring condoms?"
I thought she was joking. Then two dudes much manlier than I showed up and they were both holding ropes and chains.
Was a wrong for turning my ass around, getting in my car, blocking her number, driving home, looking her up on Facebook, blocking her there, then taking a bath and waiting for it all to blow over?
