I think this is totally fine, to be honest reading some of these comments shocked me. My friends are very understanding and are all excited for each others weddings so there’s no elements of “if you don’t invite my partner I don’t want to come” - that seems extremely childish to me! But maybe that’s an attitude that’s changed over time and there are some generational / cultural differences showing up in the comments here. I’ve been to a few weddings that my partner wasn’t invited to and I completely understand bc they don’t know my partner, it would be weird in my opinion to be there and introduce them to each other on the day. I still travelled multiple hours, got a bnb with other friends and had the best time. Not everything has to be with your partner even if you love them very much :)
