Nah thats girl code. Or at least if the situation was reversed and my girlfriend hooked up with someone, I'd rather the dude tell me straight up. What you did was okay, i think its definitely worse if lets say after you found out, you kept hooking up with the guy. So i'd say you did the right thing.

No its not bad , the poor girl deserves to know what her boyfriend was doing behind her back , and you can't be put to blame because you've had no knowledge that he had a girlfriend while you were hooking up
