Real friends tell you the brutal truth and let you know you're being stupid and a fake friend doesn't let you know?

One of my guy friends said that girls dont like him because he acts like a jerk and a pervert. He askes me why girls dont like him much or his relationships never last. I told him straight up because he was being an idiot and ladies dont like guys that act like jerks and saying nasty things. Also he doesn't respect that one girl that wanted to save her virginity for someone special and mr right. He got quiet when I told him. Well it's the truth isn't it?
