I'm scared that this guy that likes me will lose his mind/maybe go violent if I reject him. Although we live far away, and he's a nice guy, I've heard so many horror stories of people who get crazy when they're rejected, that I'm probably more scared than I should be. But honestly, I only stay friends with him because I'm scared of what will happen if I don't. He has been rejected by every friend he's had before me, and is unfathomably clingy, to the point where he would call 6 times a day. I have had to reassure him and basically boost his ego at least once a week. He's had a bad past, with a strict Chinese family and unrealistic expectations of perfection (the area I lived in was intense academically), a missing father, and bullies. He always does really uncomfortable things like posting a pic of us on insta with the caption "me and my girlfriend", when we've never dated, and whenever I call him out or talk to him about these things nothing ever changes. He makes me feel like if I leave this relationship he'll spiral and hurt himself. I've tried to do the whole "slowly making the friendship fade" thing, but he just gets clingier. Nobody I've told believes my fear, so I've stopped talking about it. He seems either mentally challenged or mentally unbalanced, and I feel more like his therapist than his friend. I feel so drained and I have no idea what to do. tl;dr: I'm worried a "friend" of mine will lose his shit if I leave and he only gets clingier.
