Why does it hurt so much?!!!

I have so many thoughts in my mind that really don't know what to write... I can't stand his presence here cos it causes unbearable pain. What he's doing is intolerable. Those words he said to his friend were the last nail in the coffin. He doesn't realize what he's done and how much he hurt me telling the strange girl that he's unhappy with me. I've done everything I could to make him happy so if he say's he isn't it means that there's no more hope for this relationship. Now he has to take care of himself cos I won't be for him anymore. Maybe one day he'll realize what he's done, but I don't think so. It's not this type of man. People say that love is blind so it means that I don't love him cos I can see.
