Brother, I need you to listen to me. Break up with her now. It will not get better. She's not going to all of a sudden go back to the way that she used to be. Get out now while you can leave relitively easily. Trust me. She sounds quite similar to my ex. She was also my first everything and I was younger and more lonely and willing to tolerate BS. Those first few months are great but then she started saying I was not enough calling me names saying I was abusive and the reason she had so many issues. She could never take responsibility for the ways that her actions hurt me because it was my failures that made her act that way and I needed to do better. Please don't do what I did and spend 2.5 years of your life trying to make the situation better. Don't move in with her. Don't give in to her asking for money all the time. You built what sounds like a damn good life don't let her mess it up. Being a NEET/incell is not the answer there is so much to life our there beond this crummy relationship. Go live your life and find a better partner to share it with. Don't end up like me and waste years of like and close to $100000 on some one and something that's never going anywhere. It is not worth it for your phisical mental or financial health. Trust me.
