Lately I've been thinking a lot about my second ex, he had multiple personalities or as some call it DID. My second ex and I used to be very happy with our long distance relationship, he was a great guy until one weekend when he came back online we had an argument about me being insecure and doubting him, he then became distant and blamed me. A few days later he told me that he had been trying to break up with me because he felt guilty that he didn't love me anymore. I asked him why, and he said "the part of me that loved you just vanished, I realized I'm not the person I thought I was, I'm a bad person who would leave someone right when they needed me most." Or something like that. After that he basically erased me from his life and told me to erase him from mine. I tried to be friends with him, but he changed after that and started to be a bad friend, in the end I told him I hated him for lying to me and breaking all the promises and future we had planned together. But lately I've been wondering can Multiple Personality Disorder really cause love to just disappear? Or can a personality randomly vanish or be killed off? Because back then I felt he really did love me before that happened.
