I have an ettiquette question when it comes to addressing the inviations. My fiance has an unmarried family member who lives abroad. This guy was dating a woman for several years, but recently broke up with her and is now dating (possibly engaged) to someone new. At the time when my fiance gave me his side's guest list with addresses and and names, under this man's name it had invite two, so I addressed the invitation to him but in his RSVP card I put admit 2.
Now the issue is, my FMIL is arguing that its not right, and that we should re-addressed the invitation to him AND her, because not including this woman's name on the envelope would offend her. I don't see it that way and neither does my fiance nor other persons we asked about it. Its not that we are NOT inviting her because the assumption is that since the invitation is addressed to him and he is dating her, that his plus one would be her. Keep in mind that my fiance's family didnt even know this woman's name until about two days ago.
