Yep, the WW fantasy bubble is strong. My W, like yours, wasn't ready to blow up peripheral relationships. Like the one with my mom, and sister, and mutual friends, and church members. In fact, sometimes I wonder if that is the only reason she stayed.
Lol my WW is absolutely livid that my family isn't really talking to her. They are being cordial. She says incredulously, "I got so many gifts for them and they do do this in return?". She ignores that she cheated on me and is asking for divorce. Apparently she is entitled to a familial treatment from my family members even now.
