What's the most obvious hint a girl was interested in you but you missed all the signs?

My ex girlfriend had told me that she was out with friends when really she was out cheating with someone, and she wasn’t responding so I texted my ex’s friend asking where they were/what was going on, and she knew what was going on and told me to come over to her house. I had thought something bad had happened with my ex but really it was just her, and me ex’s other friend she said she was with, and they told me what was going on. I was so distraught and angry about being cheated on I left after they told me and had sunk into some bad times, anyways this was maybe 8 years ago, I talked to the friend that broke the news to me not too long ago, and she told me both of them were counting on me having a threesome with them that day right there. I missed out on a revenge threesome with my ex’s best friends because I was too caught up about being cheated on.
