...PRESSURE .... remember pressure gets them all spun up. I am guessing (mind-reading) that your W will be hot and cold till this birthday party she has opted to take over is all done. Currently that's where her focus is .... and yeah, they want us to still be friends, helps them with the guilt of what they have done and the damage to the entire family that they have inflicted.
Remain detached, do not let her suck you in .. its hard. Stay the course.
