W makes all these little promises and breaks them. Especially to her D's...my gosh...even at H's worse (out all night long) he still called the girls to tell them goodnight). She is just wrong. I am sorry. She knows you are miffed but you weren't generally rude to her. She deserves it from you, really she does. I think your W is still in selfish mode, wants a bit of everything (family life and single life). I see that in my H as well.
Keep living jar's life, being there for your girls. Good things will happen.
