Heres how it came to be that i showed my current girlfriend pictures of my ex girlfriends who are much more attractive than her. 

     So i would consider myself a slightly above average looking guy. Im fit, tall, and have a good personality. Over the years i have been with my fair share of attractive women. But the girl i am with now is the woman i undoubtedly want to marry. I love everything about her in a way that ive never felt for any other woman before. 
     That being said, she is definitely not the prettiest girl ive ever been with, be it hooking up or long term dating. She's what i would consider averagely cute. We know quite a bit about each others sexual history but there are a few women ive been with who she has never seen before that i would consider super attractive to downright gorgeous. She has only ever actually seen 2 of the girls ive been with before her. One of them was a drunken one night stand and the other was an actual ex i dated for over a year. The one night stand was not my proudest moment.
     So whenever we argue or fight she has this argument that she likes to hold against me. Along the lines of "i am the most attractive girl youve ever been with. You never have been and never will be with a woman whos better looking than i am, so you better get your shit straight because you have no where to go from here but down." And she uses this as her primary argument in a somewhat threatening and very mean kind of way to try and make me feel bad about the women i was with before her. She has even taken to pulling up their pictures and pointing out their flaws in comparison to herself.           
     So the other day i had had enough. I told her you know what? Ive never showed you these girls out of respect for your feelings and confidence but here are some of the better looking girls that ive been with that ive never told you about. And i showed her some of the girls instagram profiles. As you can guess it didnt end well, we only fought more now she has that to live with for the duration of our relationship. But i was sooo angry and so sick of "these ugly bitches i used to be with" always being thrown in my face i couldnt take it anymore. And thats about it as far as that went. What do you guys think? Am i the asshole?
