fiancé received wedding invite without my name on it

in a bit of a predicament and curious other people’s thoughts. some context: A is a friend/former coworker of my partner who i’ve gotten to know over the past few years and am friendly with. she’s come to my birthday/housewarming parties, i’ve gone to hers (with my partner), etc.

we got engaged in august and sent a save the date, addressed to her and her boyfriend. they got engaged a couple months later and just sent their save the dates, and my fiancé received one that was only addressed to him. i assumed this meant i wasn’t invited (which is okay, people make these decisions for all sorts of reasons), but my fiancé thought there’s no way she would invite him and not his long term live-in partner. the zola link for collecting addresses also only had his name listed. my fiancé says that surely I am invited and my name will be on the formal invite.

i guess we’ll find out for sure when she sends formal invites in a few months (her wedding is also happening before ours), but is this standard? just curious since I made sure to include SOs on the Save the Dates, but maybe not everyone does this?
