Search Results: wait to call

29F, we have been speaking for maybe 2 weeks but haven’t spoken that much, in the sense maybe 1-2 replies a day. And I guess that is somewhat my fault, I only check the app in the evenings & that’s when I send msgs. He gave his # when I asked if he had social media & he doesn’t, that’s when I said I’d prefer to wait a bit longer before sharing my # & he seemed to understand. He asked if I’ve been to this local restaurant because they have great sushi & he thinks I’d like them, we confirmed the time earlier this week. It’s odd because I say I prefer hinge based off the conversations & guys I seemed to “attract” from the app but never actually met up with one in person. I feel like if I decide to meet him tomorrow, I’ll no longer have this higher opinion of the app. And while I know all the apps have good & bad, I’m still kind of wary. At the same time, my expectations of this guy are non existent, when he gave his number I did a quick search on him & no criminal record/no social media found. I just feel like I’m kind of used to speaking to the guy (s) a bit more on daily basis before meeting up, I asked if he wanted to do a call prior & he said he was fine either way.

A guy I've gotten to know and I often engage in a lot of banter.
We have the same sense of humor, so we often call one another ugly names and then laugh our asses off.
He calls me Quasimodo, I call him Dickhead. It's something we thoroughly enjoy.
We don't hang out outside of our mutual community, but we do often spend time together when we're there.
Recently I joked about his behaviour to which he replied "but you still love me" then waited for my reply. I pinched my fingers together a eventually said "just a tiny bit, but only if it's mutual," he replied by pinching his fingers like I did and said "just a tiny bit". Give two playful punches in my belly and walked away.
I jokingly exclaimed "Hey, my baby!" To which he replied "Doesn't it sit on your backside?" Referring to my ass. I laughed along and said it was a conjoined twin, and the two of us kept joking about my "twins" for a minute before I left.
We have interactions like this more often than not, which is why I thought he might be interested. However, I just now learned he is in a relationship with someone.
Is this kind of behaviour normal when you're in a relationship or would you consider it (emotional) cheating or whatever term you'd use?
