I work with a group of volunteers (about 8) about 1-2x a month for a non-profit. We didn't invite them to the wedding or reception because we needed to keep it small and if we invited one of them, we'd have to invite them all. They all know we're getting married - we've even already gotten a gift from one! But then now they all know they're not invited too. I feel sorta bad, and I'm not sure if I even mention the fact that we would have loved to have them all at the wedding, but it's just a real small thing? Or do I just continue to not say anything and accept their congratulations? Not sure...TIA.
