How do I not let this control my every thought?

[Travis]

I do have an attorney. Most of our conversations go through our attorneys. I just try to be civil with her because, like it or not, I have to be some part of her life for the rest of our lives. Even though we will be separate, we are both still parents to these kids. And I do my best to be civil to her, but then she always pulls these b.s. moves and it just pisses me off. I'm just about to the point of saying nothing to her whatsoever, letting the lawyers deal with it, but I'm a better person than that. I put up with a lot because of my kids. I can handle it, but I won't be pushed around or stepped on. There is no reason two adults shouldn't be able to get along for the sake of their children. But she just seems to be using it as another reason to try to fight.
