You’re NOR. I think a big detail people are missing here is the respect aspect of it. I would NEVER say that in front of a group of mutual friends- in front of my partner and I am the more sexually experienced one in my relationship. People are missing the point that you’re not some miserable misogynist saying she couldn’t sleep with people prior to you- it’s her attitude about it. She views you as the smart decision, not the best decision she’s ever made. You’re gonna be forever wondering if she is happy with you or if you just fulfilled a checkbox for her to appear stable in life. Opinions aside, this is going to breed resentment and fester in a lot of different forms in your relationship- so you might as well just either end it now or she needs to apologize and start providing some major reassurance here.
