Met a girl. We both had feelings for each other very fast. She's very intelligent and we share so many personality traits. Spending time with her feels special.

She is very upfront with me about how she has a gigantic n count, and views sex incredibly casually, and has even slept with some abhorrent people because she found them attractive. She has been very very honest with me, and even though she wants my commitment she has not told me positive white lies to win my favour. She claims now she wants a committed relationship and that I give her tingles. This I can tell is true as I can see it in her face.

After 4 amazing days together, I break it off. I can't handle the way she sees sex. I'm promiscuous too and seeing many girls at once, even while I'm seeing her. What is my problem? Why am I so hypocritical? Am I throwing something away? What would be your reasons to justify staying or why would you leave as well? I just get this revulsion in my stomach I can't explain and it feels silly. Thanks in advance

EDIT: Just read through all of the replies and carefully considered each of them. Some of them were quite reassuring. For objectivity sake, it would have been nice to hear from some people who have had successful relationships with high n partners, but it wouldn't change my mind at this point in my life nonetheless. Thank you so much for engaging!
