What's your goals? I don't see how calling her a liar and ho would help you further them? I assume you either are open to reconciliation or if not, at least want to have a decent co-parenting relationship? I don't think those kind of comments will get you there. But I had a time or 2 when I acted like that, too. My feeling is it makes it easier for your W to detach and justify her behaviors when you treat her like that.
