Following is list of the most common forms of address. If you know the persons names, I'd put both names on the envelope-and send it to the ones your actually friends with or better friends like, Mr Jon Doe and Miss Jane Doe If though, they are both good friends and you'd be inviting them both even if they weren't dating, its nice if they get a separate invite each. Generally, an invitation to parents and children is addressed to the parents: Let them both know that you want them to celebrate with you. It is often best to find out what she prefers to go by. I dont want a misunderstanding in case of a breakup.

Q&A: Invitations: Addressing One to an Unmarried Couple?
Invitations are always addressed to both members of a married couple. This rule no longer applies. Are you a vendor? No abbreviations or middle initials are used when addressing formal invitations. Your brother's girlfriend probably knows not to go to the wedding if they break up, but that doesn't mean she wouldn't be hurt to be called "and guest" after spending Thanksgiving with your family.
