My girlfriend (who is my absolute ride or die best friend) will never lose a fight. I know this isn’t the craziest subject, but it’s worrying me more and more as time goes on. We will start a fight, (rarely but enough to want to seek advice) and she will shit relentlessly on something I have said or done. I will explain my reasoning very politely, intentionally extremely politely as to keep my hands clean, and after a little back and forth, I will apologize every time, as to be the peacemaker. I would rather have a pleasant time with her than argue semantics, as would most people. I don’t want to submit without sharing all of my opinions though, as to not be completely run over. After my best attempt at a sincere apology for hurting her feelings, (phrased in the best way I know how at the time) she then deliberately chooses something else about my explanation/apology to pick apart and further attack me with. I will do my absolute best to resolve a situation as politely and understanding as humanly possible, and it’s truly impossible sometimes even when I’ve owned up to my own actions, which I always do. I don’t know how to make peace with someone that’s genuinely looking for a fight. Anyone have advice or experience with something similar? How have you dealt with it?
