I was unhappy in my marriage. Spent years trying to improve 'it'. Decided to improve myself. Stopped caring if she got upset over little shit. Started ignoring the tension and making myself go do fun things I wanted to do, in it's place. I thought things were improving. She then disrespected me. Not with words or body language, but walked out in the middle of a discussion and drove a state away and didn't come back for 2 weeks. (She has family down there) I didn't call her, and we had very limited contact. After a week, my life was good. Stress and tension were gone. It was easier to focus on the things I enjoy. I filed for divorce. It was final on Friday. She came running home and tried to fix things, but I stuck to my word. Now we live together, and she swears things will be better. I have my doubts, but next time she leaves, finances have already been split, and she'll have no reason to return.
