So I get it, you should invite signigicant others. What if you have strong feelings against that SO? This individual does not live with her, is in his 50's and can be counted on to show up at any party. He has a history of causing damage to peoples' property while drinking, on more than one occasion. Again, it is not the typical couple... just someone she calls her bf for the last several years that she parties with. Who am I to judge someone elses relationship you might ask ? Well I happen to be someone who is personally dropping tons of money on a wedding and as such is trying to justify why I chose not to invite someone who could send it all up in flames (quite literally based on his history). Especially see a conflict with self control and our open bar... So I didnt tell her why- I just didnt give her a plus one. And when she added one onto her RSVP anyways, I told her nicely that I could not accomodate her guest. She is not bright enough to really put 2 and 2 together to realize that anyone in their right mind would not want this guy at their wedding, so she doesn't understand why she doesn't get a guest. If she pushes me any further on the issue, I intend to tell her the real reason. While under no circumstances will I change my mind about inviting him, I wonder if any of you can relate and how many of you think I am an awful host. There has to be some grey area, am I right?
