its all about control freakery. dubs just love shunning--it really strokes their self centered attitude. so if they can rub your nose in it--by excluding you from their sweet little holier than thou family get-togethers--it bloats their religious cult mindset.
just let them get on with it..dont do anything that sets them against you even more. your daughter is right in the middle of it. not her chosing..not yet.
