I'm glad you're doing well.

Try slowing down. For example, you just got an insulting text from your ex-wife. Your first urge is to fire off an inflammatory response, and then before you know it, you're in the middle of your own personal nuclear war.
Don't answer it right away. Think about the matter in practical, rather than personal terms. If she calls, ignore it until you've had time to calmly craft a strategy.
It might be that calmly giving in - or compromising - might unfairly cost you a little money, or you might feel like you've been taken advantage of, but getting in a huge battle and digging in your heels over something that really isn't going to harm you in a practical sense isn't worth it. And it will affect your sobriety, worst of all.
Not saying you should let people push you around, but if you keep your powder dry, and only fight when there's something consequential at stake, you'll be happier day to day, and you'll also more effectively defend your interests.
If you're more accommodating about relatively minor things, then when you *do* put up a fight, people will know you mean business. When you get in a giant pissing match over every little thing, people don't you seriously.
But above all, try to already things as strictly practical problems rather than assaults to your pride.

This one tip is a gem. I like it because it was so helpful to me. "Limit the time you spend paying attention to them." Anger/resentment are self reinforcing bad habits, and they can be broken." As you limit paying attention to them, you will get better at it, and eventually stop doing it when the benefits of ignoring them become apparent.
