Provocation?

I was reading Reddit earlier and a post in a Men's sub asked the question about turning down an attractive friend.

I instantly thought of the evening that E3 kissed me, at the end of M's birthday party. What I didn't put together until today were the parallels between that evening and the first night I kissed FA2.

On the evening I first kissed FA2, I was out with another group of people that included FA1. FA1 and I had a bit of chemistry, but I could never tell if that was translated into actual romantic interest. BW was meant to be out, but there was no sign of him when we all met in the early evening. Eventually, BW turned up, with FA2, nearly three hours after the rest of us had met. By that time, I'd been chatting to FA1 for a while. I'd ruled out any interest on her part due to the fact she'd recently started dating a new guy. But as I said, we'd always had chemistry, so the conversation flowed easily, and that was how BW and FA2 found me, deep in conversation to the point of being oblivious to anyone else around us.

At M's birthday party, while there was a group of old school friends in attendance: G,BR,E3 and others, I was being more of a social butterfly. I was chatting to some of MM's friends, including MMBF who was looking mighty fine in one of her figure hugging dresses. There was a bit of low-key flirting going on. Both M and MM knew that I had a bit of interest in her, but I think we all agreed that we probably weren't suited from a personality perspective. On more than one occasion, MM's friends had me on the dance floor.

There are strong similarities in both nights - me being fully engaged with other, attractive, women. So, it struck me earlier. Was it my behaviour with MMBF and FA1 that prompted E3 and FA2 to make their moves? Another similarity was that I didn't see a lot of E3 or FA2 at that point (that changed with FA2 after this night though).
