cheating or not?

I met this guy lets call him (David) at a house party. I recognised him from instagram, as he dm-ed me once but I left him on seen… I pretended to not know him and introduced myself. We were both crossfaded and ended up getting intimate.
Anyways, two days pass and he adds me on snap and we end up talking, and then hanging out. I get to know him as the sweetest and most caring guy before. Fr, no one has ever treated me like this before.
However, I low-key think I’m like emotionally numb from my past relationships, and I may be overwhelmed with the treatment he gave me. Two weeks pass, and we talk about our intentions, I tell him I’m not interested in a relationship because of my commitment issues, and he agrees. We set boundaries, that our label was “just friends,” and we made it clear that we weren’t allowed to talk/flirt with other people. We FaceTime every night, text whenever we’re free, he always shouts me for our meals and I watch his football games.

I tell David how I’m going to my friend’s 18th birthday, and how there’s an afterparty. However, at my friend’s 18th afterparty, I got piss drunk and end up kissing another guy (Ricky). All my friends know about David too, and constantly tried to stop both of us from making out.

David texted me the morning after saying that he doesn’t want to associate with me anymore, and requested to give his hoodie back to his friend that could give it back to him
I understand that I broke the boundaries that I set, which made him upset, and I was talking to my friends about it, they said it shouldnt matter because he was never my boyfriend.
I feel disappointed because if I did care, then there would be some self-control with me in that moment with Ricky. Do you consider this cheating, even though no labels were set but me and David clearly liked each other?
