I met a bipolar guy few months ago and was slowly smitten and now deeply in need of him.

I love his moral character and his spirituality. We clicked but I was moving too slow and careful when we talked deep about our relationship. He wanted to move faster, though it was a long distance relationship. I sensed he wanted me to be there with him everyday we talked. He is kind sensitive and the type of man I really wanted to be with . He showered me with kind words and was eager to be together but I was afraid to move faster into promising things and I believe that frustrated him and put him in some type of depression. He is very polite and intelligent.
He got upset with me over a minor issue and I hung up the phone on him last sunday. He then called me back and left me a message to never ever call him again and that he refuses to put me through his mood swings. He pleaded in the name of god to never try to negotiate with him. From reading about this disease, I realized I was not sensitive enough and over looked his situation. He is on medication and says he hadn't had any episodes for the past years. I really want to be with this guy and I am afraid to call him back and upset him more. How do I tell this guy that I understand his problem and want to be with him? Is there a better way to approach him with out upsetting him? I am ashamed of my feeling...I even want to quit pursuing him but I am torn with the urge!Want for him...
