How does chemistry between people work?

I met this man and thought we had amazing chemistry. I think he felt it too as he'd always find excuses to touch me and we'd flirt all the time, but in a harmless way as we both have partners. All 4 of us used to hang out a lot but now they never want to go out with us. I was wondering if he felt the chemistry and got scared, but do men think like that? Would his girlfriend have noticed our connection?How does chemistry between people work?
