Gemini and Leo? Flirty?

Gemini guy always comes to the gym every day same time as me and its always very cheeky, flirty vibe between us even if its just staring at each other from the mirrors. We speak here and there just the basics hello, hows it going etc.. I find him really attractive and mysterious, he really gazes at me. Only prob is he brang an ex I assume with him once and he just ignored her the whole time and kept trying to get my attention. Are geminis known to use a ploy to get a womans attention? Its like he wanted me to notice her to cause a bit of friction to notice him even more.

yea they like to make you jealous, i dated a gem once and he was like that, alot of gamesssss
