Just throwing something out there for an opinion. I think I may have (or actually my Dad) broke and etiquette rule but i'm not super sure. So here's the story to ponder:
My cousin is getting married to someone he met in the armed forces, and she seems awesome, and I can't wait to meet her. She has been deployed for the last few months and they have many out of town guests so they sent their invites out earlier than most people would. This wasn't a problem, it gave us time to plan. The invite was addressed to John Doe and Family (my Dads name). At the time I was living away from home for school but since my parents is my home base, that was fine too (I'm back at home now anyway after starting my new job that is in my home town).
When the invite was sent I had just started officially dating my boyfriend (like putting it on fb) so they might not have even realized I was dating. Well the more my parents and I thought about the situation we realized we would really like my BF to be able to come along, the wedding is a few states away and the whole family is turning it into a mini vacation/reunion and staying for a few days after the wedding (we;ll be gone over a week in total) I would love to be able to bring along my BF so he could meet my family (they rarely are all in one place) but he was not included on the invite nor was a "guest" for me so I didn't push the issue but my parents were also wondering. He did say that he woudl love to come and meet my family but could amuse himself for a few hours during the wedding if he wasn't invited (but that seems sad

) As it got closer to the wedding my Dad finally decided to call the groom (my cousin) and just ask if my BF was ok to come. We did get the okay and boy am I glad because he is now my fiance and I would hate for him not being able to join the family!
Now I am just a bit concerned because I see so many brides on here complaining (and rightfully so!) of people bringing extra guests. I don't want to meet the bride and have her annoyed at me and my family! Did my Dad do an ok thing? Would the bride have a right to be annoyed? My cousin doesn't care one bit, he's actually excited to meet my FI. Thanks in advance!
