Hi. I have a friend who suffers from ..... I dont know how to call it,...basically,...he broke up with his girlfriend 3 months ago and he seemed to be fine with it, he was the one who helped me with my break-up, we met on a dating site.... he stated in his profile he wasnt looking for anything just chat.Since my first mail to him we skype (only writing)each other every day, but he changes moods from one day to the other....one day he doesnt want a new relationship the next day he sends me kisses and plans a trip with me, he is thankful for having me and says he likes me very much but doesnt want anything cause he doesnt want to hurt anyone, he wants to be alone...I really like him I perhaps would like more but its all magic circle....basically one day full of happiness and three days later he doesnt want to live anymore..... What is this disorder called? and How could I help him? Thank you
