Just a little update. I really feel like I have grown recently. It's almost been a week and no sign of arguing. It's like we're both watching over each other now (in a good way), taking care of each other's feelings.
I haven't even felt like arguing, and I see changes in her as well. She is more aware of my feelings, and I feel like we're more responsible now. We still have as much fun as before, but we're definitively in a better place emotionally.
I know that my ego is plotting it's revenge right now and will pop up from time to time, but that's ok. If I am not able to control it, she can and vice versa.
Thanks for everyone's advice and input. It's been really helpful
