I have a friend presently going through this but she has been tolerating this guy because according to her she loves him so much and they even have plans of settling down. How many ladies can keep up with a man that always insults you at every given opportunity, Insults like you are very stupid, you are useless, are you mad, do you think I am your mate, and then hangs up on you often. That's exactly what he does to her often times, and even after he hangs up, she sometimes calls him back because he doesn't call back. Please your advice will do her a lot of good.
