Post break up problem

[dandelion090]

So here is the thing. I dated a guy for several months. It started as a rebound from my previous relationship however as time passed by we figured we liked each other that much that we wanted to try and see where that may lead us. It was a very passionate and intense period. One day after I returned from my trip he says that he wants to end everything and to be just friends. He was crying and kept saying that he is not a long relationship type. This made me very angry since he was giving me all these hints before and I completely fell for him. I couldn't change his decision so I accepted the outcome, although it was very difficult for me.
During this period I seriously focused my attention on work and neglecting my health and over exercised myself. I fell in love with him and it just ended. He kept calling me to see me and do friendly stuff, but I couldn't look at him. I was stressed and tired and eventually I collapsed. When I was taken to a hospital I was diagnosed with a heart condition (defect which I had from birth apparently, but with the overall stress it just came up). He heard from a friend and called me, and again said that he wanted to see me. I was sarcastic and replied "Yeah sure I just have to get the results, do more tests and if I am actually not dying we can talk"

After that I called him to return his stuff, to which I received a very rude comment. After my stay at the hospital he now believes that I faked my condition and that I want to use it in order to manipulate him and make him feel sorry. I am a person that wants to leave things resolved so I tried to explain to him that that wasn't my intention but he just didn't want to see me or hear me out. Several months later I received a text message from him where he demands me to stop talking to his friends and colleagues from work. I know the people but the talk never went further from "Hi, how are you?" and it was all initiated from them.

The problem is that we have mutual friends, and after everything I am not a person that wants to hate people or hold a grudge against them. He changed completely, he is angry, talks to people impolite things about me and I think that he hates me even.
Is there anything I can do to correct the situation, or just accept the fact and move on and in the process stop full contact with our mutual friends and his colleagues?

What the hell is wrong with him? He accused you of faking a heart condition???

He sounds like a lunatic, hon. He really does.

I would ignore any and all communication from him going forward. He's just not well.

Why are you still talking/responding to this guy?
