Considering how long they've been together his wife probably was gonna a ok with it from the start considering his father is Rey Mysterio and she probably had a reaction of no way or that's pretty cool when he said his father is a wrestler named Rey Mysterio. If she wasn't then I'm sure Dom would've explained it to her and she'd be like ok I understand it's all for a storyline. Which is something feel like most wives of actors or wrestlers understand with it being for either an episode of TV, film or storyline.
