Maybe make plans in advance on the days you are off with your D and let the W know about them? Maybe even invite the W if you feel like it, but if you feel like you would struggle too much "putting a happy face on", then don't invite her. Just connect with your D. If the W tries to interfere with those plans, then enforce your boundary.
I wish i could do as good as you on the boundary setting and validation phrases.
Thanks Guzzard... KGuy, making any plans known sounds like a good idea. I have been operating as if things between us hasn't changed (when it comes to our daughter). That validation this morning wasn't easy. Constantly fighting myself to not get too involved when it comes to R talk....
