Wow Thanks for the answer! Appreciate it. Now i can rest in peaceIf you are married and give a gift to someone the same gender as your spouse and you are dating that person... your spouse will get upset, but it won't be forever. Nobody else is affected.
Yes, that's the part I said about "dating".FYI you're still allowed to give anyone a Birthday Gift, even another datable NPC of the game gender as your spouse. Also if you're married and give a Gift to a datable NPC who you didn't give a Bouquet to (to get them to 10 ), so they're stuck at a maximum of 8 , this shouldn't trigger that jealousy either.
