But yes, there are plenty of women who have friendzoned men. I'm not saying there aren't. And yeah I think it's bullshit. If that happened to me, you'd better believe I'd be pissed! But at a certain point you have to move on.
Also, if someone repeatedly gets friendzoned, like 5+ times... maybe it's time for that person to reevaluate the strategies he's using to get a girlfriend.
