Questions: Flirting

Just curious, as far as I’m concerned it’s not that attractive or hot in itself, I can even find it unattractive when it doesn’t seem justified. What’s more attractive to me is to see someone successful with a touch of self-doubt I’d say

So, this guy friend kind of invited me to his place. We're friends but he's like the "friend of a friend". I've had a crush on him for a while, not a major crush tho, though I just find him cute. He's never made a move on me, we've met in groups a few times and I assumed he was dating our mutual friend or that at least they have something going on. I've never been able to prove this tho and I didn't bother asking. But he's hinted that he's single. Long story short, he flirted with me after I posted a picture and I harmlessly flirted back. One thing led to another and he invited me over to his place to " test out something new he just got" (an inside joke). I don't mind visiting but I'm not sure if he really likes me or if he was just joking with the invite. Also, maybe he's the type who randomly invites girls to his place, I'm not even sure if he doesn't have a girlfriend like he's hinted.

I also wouldn't want him to think I'm easy. Should I go over? Or I should wait for him to mention it again?

PS: we already jokingly picked a day. I don't want a situation where it turns out I misread the signals and was excited about nothing. I screamed when he asked if I would come over.
