having no interest in relationships?? bruh

after longing for a relationship half my life, i finally got into one and it lasted around three months. i ended up being the on to break it off, is that normal? the guy i was dating was really sweet, caring, no red flags whatsoever. i just got tired of the intimacy and hanging out with him felt more like a chore, even though his constant check ups during the day to ask how i was doing were also very sweet, they ended up annoying me a bunch. he seemed to be head over heels for me, but i ended up breaking his heart. like he was crying and i just sat there like damn what now. now i feel sort of worried im a bad person and that my future relationships will also turn out meaningless, ive noticed i tend to hyperfixate on a lot of fictional characters/ people i dont know, so im also worried that this will have an effect on that. should i be worried?? genuinely wise and experienced people give me some thoughts pls.
