Feeling Upset About Last Minute Change of Plans

Did he know beforehand that this was the plan for that day? If so, you are definitely entitled to being upset, and to me, his family spiriting him away like this would be a red flag, but maybe you like spontaneity most of the time, so I don't know. If he didn't know, however, I'd give him the benefit of the doubt and explain to him what you were planning. After that, he's allowed to choose who he wants to hang out with that day, and the two of you can have your special day another time if need be. In either case, it's important to remember that your lives don't have to constantly revolve around each other's, but if this is/becomes a pattern where his family steals him away at the last second, I'd be careful. I'm the product of a relationship where one partner's family always spirits them away at the last second, and it's very irritating to constantly deal with. That being said, don't worry if it only happens on occasion, sometimes other people like to give surprises! Hope this helps ❤️
