Been with a girl exclusively for 6 months. Low n-count (1 boyfriend, 1 hookup), genuinely good girl, non-manipulative, chose me over a bunch of orbiters, im her first orgasm, regular sex, doesnt make my life difficult,greate dynamic.

The issue: her ex rawdogged her and she took the pill and puked and had to deal with that shit alone. With me she won't do it raw because the pill affected her body badly last time and she doesn't want to take it again. Medically completely valid and I understand that fully and I dont want her to go through pain duh.

But I can't get past the fact that she's been more physically intimate with her ex than with me despite me being objectively higher value in every way. Classic retroactive jealousy I know.

I've decided to end it cleanly and honestly.

Question is that is this the right call or am I letting my retroactive jealousy make a decision for me that I'll regret? And for guys who've dealt with this , does it actually get better or does it follow you into every relationship regardless? I have never given a fuck when it comes to a plate but an LTR is where I start getting such feelings triggered

Also side question , is this a form of oneitis? or is getting affected by a girls past esp one that you like a completely normal thing?
