My FI and I are in the early stages of planning and wrote our first draft of the guest list with the intent to go back over it later to see if we missed anyone. I adore my guy and all the people in his life, but he added a couple to our list that I hadn't thought of on my own and now I'm in a predicament. The couple is from our church, and "Joe" was FI's first boss almost 10 years ago, so there's a nostalgic connection there, and while "Joe" has been welcoming to me since day 1 (4 years ago), but his wife "Jane" is another story. We see them nearly every week at church in passing, and a few weeks ago when we announced our engagement, Joe came up to congratulate us and Jane was noticeably agitated until she introduced herself, interrupting the conversation. And when Joe corrected her saying that of course she's met us before, she proceeded to argue with him right in front of us. For the rest of the morning we received dirty looks from her every time she walked by. She is generally a very abrasive person who is always ready with a biting remark, so I usually just smile and keep the chit chat short, however I was completely stunned by this last encounter. Here's the kicker, she's a 40-something businesswoman, not a senile elderly woman. Every time I walk away from a conversation with her I feel so uncomfortable, and it makes my stomach twist to think about sending them an invitation. Am I completely in the wrong? We have no contact with them outside of church and the (few) other families we are inviting from church are much more invested in our lives, I just don't want to hurt my FI's by bringing this up.
