My serious boyfriend (soon-to-be fiance... he's already "holding on to my grandmother's ring") is the best man in his brother's wedding the week before Christmas of this year. His brother and future SIL are having a super small wedding of about 50 or so people, and when they got engaged/were working on guest lists, I wasn't in the picture. Side note: they've been engaged for 3+ years. The problem here is that my boyfriend's family has invited me to come up for Christmas (we all live in South Carolina, and they are from Seattle where the wedding is also being held). Also my boyfriend and I are hosting a "Stock the Bar" shower for his bro and fsil... but I am NOT invited to the wedding. Am I being insecure in thinking this is a personal snub (the future sis in law isn't very fond of me)? It has caused several heated discussions between my boyfriend and myself because we are coming up close to our one year anniversary... and who knows? We very well could be engaged by then. At this point, I'm rambling - personal issues aside, if I am going to be flying to Seattle, I need to be able to have plenty of time to make travel plans. I would love some honest feedback on the etiquette behind this situation and how to best handle this politely and gracefully on my end. Thanks y'all!
