I'm planning the rehearsal dinner and just found out that the officiant's wife was one of our GM's ex-gf (with a not so pleasant breakup, yikes!). Nobody really knows this except my fiance and I.
For the dinner, we're inviting everyone in the wedding party and their SO's, and I know it's customary to invite the officiant's SO as well... But given the situation, is it okay to not invite her?
