Mystik--if you normally do avoid conflict, it is a 180 to inform him that you will have S for Mother's Day. Do you have S on saturday night? If so, you could just text your WH that night and tell him (after S returns to you for the night).
You should know that with regularly divorced parents--it is a given that the kids are with their Mom on Mother's Day!!!and their dad on Father's Day!!!
Tell us how you think your H would act when you tell him.
