I was in a very serious relationship with a guy for 9 years. we were living together for 7 years. just like any other couples we also had our share of problems & disagreements. last December, just short of 20 days for our 9th anniversary, the guy broke up with me because he felt that he would completely lose me because of all our problems. we broke up. time passed by and I got to know that he was dating some other girl. but his relationship did not last for over 2 months. I have Moved out of blor now. but my ex has turned completely crazy. he Cries all day, doesn't eat properly, has gone broke, keeps talking to himself thinking he is talking to me, keeps using the particular language we both used to talk in. I recently got to know about his mental state and as a human, I am really worried for him. he keeps pinging me on Watsapp and I have to reply inspite of not wanting to talk. I feel he is in serious medical Depression. what to do? please suggest. I am Really seriously worried 4 him.
