Am I too protective of the last guy I was with?

I met a guy online last year and spent a year getting to know him and then traveled from Australia to the UK to meet him. I stayed 2 months and fell deeply in love with him. Now Im back in Australia Im worried since hes 74 and has causal sex that hes too trusting and that he might get hurt one day. Im aware its his life but I fear for him all the time and his safety. Also He told me he was into S+M and that guys had hurt him and he enjoyed it. It had the reverse effect on me as Im very protective of him and the idea of some sadist hurting him enrages me and makes me want to hurt them. Am I overreacting on this?? I Truly love him even from afar and I wont ever stop loving him despite being told by him to find somebody else. I deeply feel there is nobody else that will come up to his standards nor open my heart to anyone else ever again.|||I think u two are not compartible with eachother therefore he told u to find another, unless u enjoy s m as well. Also, he chose his lifestyle over a possible relationship with u, so move on and stop talking to him while try to get over him. How old are u btw?|||It is an overreaction to want to hurt someone because of consensual sex that is not any of your business. They enjoy the sadism and masochism, and you have no dibs on this guy. He has moved on and is choosing casual sex over you. It sounds harsh, but it's true. Time to be a big boy and move on.
