I started addressing invitations recently and I have been addressing single and non married couples starting with Ms. and Mr. I think it's more formal and respectful to give everyone a title. However FI and I just received a wedding invitation and there was no Ms. or Mr. before either of our names. I feel a little offended because why should married couples be the only ones with titles? lol The wedding is not a casual affair either, so I'm not sure why titles were not included.
How is everyone addressing their invitations to single guests and non married couples?
