<human>: Condense the text into a few key points

Alright so this is an odd one. Before we started dating (we've been dating for about a month) we were essentially friends with benefits. Over time we started to become closer and eventually sat down and had a conversation about moving beyond just fuck buddies. Part of that conversation was me telling him that I was fine with him sleeping with other people. The reason I brought this up to him was because he has an EXTREMELY high libido (he himself genuinely believes he is a sex addict, and has talked about going to speak with somebody about it) and frankly isn't the kind of guy who can only sleep with one person (and I'm actually totally fine with that, as long as it's just sex). During that conversation, his exact words to me were "I've had my share of fun, but at this point I'm ready to settle down".

 
So fast forward a month. I'm under the impression this entire time that the relationship isn't open. I'm playing a game on his phone and a text message pops up, yada yada yada he's been messing around a LOT with multiple people. Now I'm confused. I mean, I did give him explicit permission to sleep around, but I feel like the moment he declined that permission it became cheating to fool around with anyone but me. 

Help me make sense of it all!
<bot>: I offered to let my boyfriend sleep around, but he essentially said no. Then he went and slept around anyways. Did he cheat?
