Hey Garrett, I am happy that you are not into suicidal thoughts anymore. I understand that it is very hard to be in such a situation where you love the person wholeheartedly but the other is not really that interested. I guess it is the change in situation (in this case going to China) which has led him into those unacceptable habits. I think you should retain your individuality and not give it up at any cost. Being emotional is not at all bad but just dont let people make use of it. Take a break from the thoughts and spend quality time with yourself. Let the dark clouds pass. You must be a wonderful friend for you value the relationship so much despite the odds. Your friend might become the same old person some day. Lets hope that it happens soon. Even if it is not going to happen, do not regret. He is the one who will be at loss. He will be missing a true friend.
