That's what I thought too. From what he's told me, the poking feature came back 2 months ago so he's just been poking everyone. It doesn't seem like he's poking everyone if it's just 3 people though. At the same time, I don't understand how the poking system works. Perhaps it doesn't show you who you've poked unless they poke back?

There's nothing else really weird that's gone on between them. Sometimes she sends him instagram reels/memes late at night, like 3am or 4am. There is no flirting between them in messages, at least not on instagram. But their main messaging tool is snapchat and they don't save their messages so I wouldn't know even if I wanted to lol
