This is a tough one. My wife tried to tell me for years i was bipolar, and i flat out refused to believe her. It took some extreme stuff to get me there. In the end a lot of what happened could have been avoided, however no one, and i mean noone wants to hear this about themselves. Denile is not just a river in egypt. LOL LOL LOL
My advice as a man is help him understand and explain the consequises if he doesnt get help. You have to mean it that you will leave, and even then it may not go as you plan. Good luck, this will not be easy.
