We met half year ago, online, and liked each other a lot. Our relationship had ups and downs, and I felt he wasn't completely sane from the second month. For example, at the beginning he was absolutely paranoid of me cheating. He could accuse me of having cheated without any proof. He was very possessive and jealous, not wanting me to talk to any male. Besides, he could tell me from time to time that God spoke to him. One day, he told me he was laying on the bed and started having visions. He has the belief that some people are possessed by demons. After our break up, he told me he struggled with anxiety and mental issues, and started feeling he was infested by worms. He told me it was due to the stress of the breakup. As far as I know, his grandmother suffered from schizophrenia all her life. Over time he started to trust me more and not take anything I say as if I wanted to attack or harm him, but yet these delusions still stayed with him. I became very concerned about the things he has been telling me. He admitted having problems socialising with people. The relationship ended due to how much pressure he was putting on me, he didn't want me to study, I had to always think like he wanted me to think, otherwise it would become a fight... I felt overwhelmed. But yet, I'm still worried about him. What's going on with him? How can I help him from the distance?
