TBH, you have to work for it. It doesn't stop on its own. You have to learn new coping and communication skills, ways to fight fair when you argue, she can't pull the emotional blackmail bullshit and you can't be a bully with the fucked up language you use to put her down when you feel backed into a corner. And it's not good for the girls to be around either. If you guys were going to get serious, counselling is the only way to go. Even if you do it individually. It's better than nothing.
