Search Results: how do i keep his interest

So there's a guy i accidentally started chatting to on the dating app im on. he's not after anything long term and i wouldn't be interested as he has a kid but as i found him attractive i swiped right when he didn't have that on his profile.

He told me straight away what he was after, without any of the crap i had before that they wanted to meet without saying what they wanted.

I told him the truth about never done anything before and my health and that if he didn't wanna continue talking he didn't have to.

Now he hinted that i could use him as a way of preparing me for whats to expect when it comes to guys. I did say i have attachment issues but we did agree if it did happen thered be no kissing or dates etc

Only thing im concerned about is im saying there won't be anything risky happening but im not sure if he would be hoping for more.

I've said if were still talking by the time my birthday comes around (14th) that we'd meet for a drink not far from where i live (obv im not gonna tell him that) and see what comes of that

He sent me a few pics, one with pants and one without, even tho i did say to keep them on. But the last pic didn't reveal anything and they put a block on photos too risky

Tried to find him on fb to no use and he obv split from his girlfriend and has court orders (but then my brother does and he hasn't done anything wrong)

For context, we met up for first time from app yesterday & had two calls earlier this week. I was questioning if he was interested to begin with bc with the calls earlier this week, he’s the one that ended them in less than 30 min. And yesterday, he ended the dinner too because he “knew I had somewhere to go & didn’t want to hold me back” (told him I had to go out of town with family & would need to leave in the night). I haven’t heard from him since, he drove 45 min to meet me at a local restaurant, paid for the bill, walked me to my car & hugged me twice (in my opinion all common courtesy). He asked most of the questions, by now I’m just used to the guy reaching out maybe an hr after meeting up telling me they want to see me again or at least wanting to make sure I got home safely. I deleted the app yesterday but still have him on discord, he shared his # when we spoke on the phone earlier this week but I hid mine for safety reasons. Honestly I’m not interested in seeing him again, I just hate rejection. Also when we were msging earlier on, we didn’t talk consistently throughout the day like I’m used to with other people I’d speak with in the past. I’ve become lower effort in that sense bc I’m not as invested but if a guy is interested he’d pursue. Last thing I’ll add is he asked me maybe 2-3x if I had new years plans & kept telling him not sure yet/might do something with family. I can’t anymore 🙄. I’m giving it a week & if I don’t hear back from him, I’m deleting him from discord.

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?
