Losing feelings for her??

Hi, for context, I am 21M, and she is also 21M. We were classmates, then we shifted to different countries, and we were good friends and on good terms. She was dating someone, and I was also dating someone. Later, I had broken up, and she also broke up with her ex, and she was feeling alone, so I offered to be on call with her (P.S., this is me in uni, taking super easy courses ). Later, we spent a lot of time together and figured, why not date?

Skip to present its been 2 years, and I recently spent a month with her ( delaying my internship to go visit her ) and after a 2 weeks spending time with her, I did not want to kiss her anymore, i was repulsed. I thought she was cute, but at the same time, I did not want to be near her. We did spend all the time together, I figured maybe cuz I needed some space, and once I go back, it will be better, but here I am.

She did tell me she was a lot to maintain, and she needed a lot of attention. Back then, it was fine, but now I am graduating and also working.

I am skipping my time in the gym and work to talk to her, and we fought about it before, and she said, " You don't love me anymore ". I think it's true, and I thought about how it would feel if we broke up, and honestly i would have more time, and I can do my stuff, meet my friends, and be more active. She knows this, but I do not know how to bring it up. She starts tearing up, and I am to scared to have confrontational talks cuz I feel I made her that way, but I do bring up things that make me uncomfortable, and she also understands.
