Search Results: hard to notice flirting

I know he liked me in the past but he never asked me out so I grew bored and lost interest. But I like him again now and I have shown signs of interest and flirted back with him so I know he has somewhat of an idea that I’m interested in him. Sometimes, he will be extra flirty and make his interest super obvious but then on other days he seems to avoid eye contact and then at other times it’s like he’s trying so hard to get my attention. He flirts with me more often when I reciprocate and when I act like I’m not interested I notice him looking/stealing glances at me more and showing up to places I’m at to be near me and we will catch each others eye but he doesn’t try to flirt. By flirting I mean he locks eye contact and smiles while gazing at me or trying to talk to me indirectly through a group setting. I cannot tell if he is shy or just playing games because I’m getting so many mixed messages.
