Welcome! You never know what might happen; delicious food is a great persuader, and you are in the right place for inspiration on that score. My partner used to be pescatarian, and then he was vegetarian, and now he's been vegan for 6 or 7 years. (Everything has turned out according to my plan - mwahahahaha!)
damn, after 14 years, I haven't even compelled my fella to downgrade from omnivore to pescatarian! You're more persuasive than I am!
(but, he does love my cooking, so that's great)
