It's All Relative
Once, I went to a Shabbos meal that was also attended by a guy who I had dated for a long time (in shidduch terms) and his girlfriend and the ex-husband of a friend. It was very awkward. Essentially, I sat between two friends and didn't say anything to anyone else the entire meal.
The good thing about having said experience, though, is that pretty much any other awkward Shabbos meal pales in comparison.
