DH's ex is a SAHM to school age children whereas DH works full time.
She wants him to speak to his manager about changing his day off so he can take the kids on a different day to their usual schedule so she can go out on a particular day because that day works best for her friend.
AIBU to think she's a bit of a CF and should make plans for the child free days she has rather than expect him to miss work to accommodate her friends?
