<human>: we are both 21 and have been together for almost 3 years. 

So my bf has been depressed for a while now. I can see it, his family can see it, my family can see it, but he can't see it. He wont admit that he has a problem. Recently he has been talking about how he is going to kill himself in the future and this scares me a lot. I have told him many times how I want him to go to therapy, but he just keeps saying that he doesn't have a problem. He also gets insulted when I tell him he needs help. It has gotten to the point where I am very worried about him, and just want him to get better. Is it acceptable for me to give him an ultimatum that he has to get help or I cant be with him any more?
