Does this really count as cheating when they're not even dating????

I mean it's his body he can do whatever he wants no one owns him

Well i called it cheating because people did
BUT the situation here is so dumb
He didn't even get rejected by his crush
And the seme clearly showed how important the uke is for him
Why would he sleep with sb els right after that:/?

Well you can say it's cheating. Bc seme clearly confessed to him. And knows uje loves him too. And then they had sex, in the morning they both could make it official by talking. But this is where the problem starts, coward ass uke ran away w/o talking to seme, assuming and feeling insecure that he'll leave him. And went to another guy to have sex and feel secure again see the mentality is sickening. He can easily talk it out and make it official, but his excuse of having sex was feeling insecure. Does that even make sense?! NOPE. avoiding conversation, assuming shits on their own, making insecure and not sharing and to relieve from that having sex w another guy just afyer havibg sex w his so called many years of love. Lame and disgusting.
