It isn't cheating yes,but you can't help but still feel betrayed

It's good but I just can't accept the fact that he slept with another guy and the second one does the motel doesn't have anything like a key card, password or what??(Sorry idk much about that so idk)how come anyone can come in so easily like that?or the one in that red paper that he gave away has a password or what?cause just for real that shitty scene felt so stupid,I'm already pissed off about the first one cause he's the one who bring that man but I kinda understand him but the second time he did gave him that red thing before but lmao? how come he never changes a number room or just lock the door?it just felt so stupid and unnecessary
