Confused about love!😭😭

So i started talking to this girl about 3-4 months back. we’re both 19. same clg. now she started giving hints n i understood n took things forward. initially it was just my hormones kicking in cuz of which i took things forward. now she’s not really my type (im the clubbing biker kinda guy and she’s very calm composed and homely kinda girl). she’s genuinely very sweet but i don’t wanna take things forward. she genuinely loves me but i just don’t have that feel now. i know it’s not to late right now to end things but i genuinely don’t wanna break her heart. Continuing this to the shaadi wala level also wouldn’t be possible because totally different family backgrounds (states wise). Help me figure this shit out. I genuinely feel like a dick but i don’t wanna hold her back from finding the right guy. 😭
