My fiance and I have 2 friends in our social circle who just happen to be dating. We are friends equally with both people. They do not live together. If they break up, we would still invite both friends to the wedding.
Do we send each friend an invitation individually? Do we send an invitation to only one friend and invite the other as part of the couple? If the 2nd answer, how do we decide who we send the invite to? We want to make it clear, without a doubt, that these friends are both invited, regardless of their relationship status.
