Her complaints from what I've gathered:
That I never focused on her, she always came second.
We didn't do enough things together.
I kept her from being with her friends, and made her feel bad about going out.
That I've controlled her.

What I think she found in the other guys?:
They spent recreational time together.
She could do whatever she wanted.

I think that spending fun time together, is a HUGE reason we are where we are. I ignored her for a game, and our relationship fell apart.


Well, as I was typing this saying what I thought she felt, I just went ahead and asked her. Here is her exact response:

i don't like that all of the important decisions for my life in the last 4 years have been dictated to me - I HAVE TO move because "I'm married" I HAVE TO buy a house, because that's what married people do, I HAVE TO give you half my paycheck...
i'm tired of doing things because other people want me to
i just want to be my own person for a while...
that may sound selfish to you, and you'd be right, it is. but you know what, i'm ok with being selfish for once

And regarding me:
i don't like how skinny you are, i don't like how you force your opinions on people, i hate that you always feel you're justified in everything you do
i hate how mean you were to my friends, i hate how you always act superior to everyone else
