The level of selfishness the WW often shows is beyond irritating. Thing is .. just like all things, you can not control her nor what she does. She is creating this right? All you can do .. is just what you are doing, being the best father you can be, be the rock. You gave her a serious truth dart with the "I expect you to put the kids first" line .. let that soak, marinate ... what is done is done, do not let it mess you up here.
Turn this into a positive, go home ... grab the kids and do something spontaneous and fun .. grab a ball go to the park .. whatever ... make a memory in spite of her behavior.
