My FH and I will be doing a rehearsal dinner after the rehearsal to show our gratitude towards all the people (parents, bridal party etc) who has helped us along the way and who play significant roles in both our lives and our wedding.
I would like to know if it is necessary to invite our bridal parties significant others? I hear that we should as if their significant other play a role in a wedding it usually effects them as well (which I totally get) but does that only apply to engaged/married couples?
