So my husband and I are being thrown a BBQ by our in-laws as a belated celebration for people who didn't come to our wedding in Arizona. We had a small COVID wedding so we had 35 people and that was it. They wanted to have some people over just to pop in and say hello. We've been given the option to invite co-workers and we decided on a select few we each are close with. However, there was a former co worker I decided not to invite because 1) since she quit, she created drama at our office place and I don't want that around our celebration 2) we're not as close anymore. I am worried that it will get back to her. What do I say if it does?
