After all the years I've been on these boards and all the shit I've read, I'd say HELL NO.
I can't even tell you how many drama threads I've read with a brother venting because he told his girlfriend at the time, and she tells his friends, family, boss, I even remember one, after the couple got in a fight she grabbed his gear and took it to the police and tried to get him arrested. If it's a girlfriend don't even THINK about it. If it's a wife or soon to be, she'll have just as much to lose exposing it as you. Everything is a seesaw bro it all comes down to who has more to lose.
