Thats possible, but its also possible he DOES know. Most of the time we know when women we are dealing with have a boyfriend. So spare me all that crap... and we're talking about raw human emotion in the heat of the moment. Sounds good to act all cool like you wouldn't care about your wife getting plowed, and walk away calmly, but you don't know how you would reactWhy would you beat the guy? If the dude thought she was single, and he didn't even know you.. Owes you no loyalty.
He is getting laid, like the rest of us get laid.. If puzzy is available, we aim to smash.
The only person you should be angry with, is your hoe of a wife lol
