My finance and I are working on our list of who to invite to the wedding. We have it down except one person that we keep going back and forth on. He wants to invite his friend that has not been particularly friendly to me (and I only use "friendly" since all other words would be inappropriate for the boards). I am completely against inviting them. I have a feeling that they are already assuming they are invited. How do I prevent a disaster between me and my fiance? And how do we tell someone that they aren't invited when it's clear that they think they are? This is something I am firmly adamant about.
