Invitations for Couples who are dating!?

I'm gonna address it to whoever I know better and just put and guest..but if they are dating and living together I will address it to both..just because for me I feel like it's awkward to add someone to the address if they aren't living there..maybe you could put it in parentheses or something? I know though some people are really particular, like if the couple breaks up by your wedding they may snag another date..it also depends if you are close with both of those in the couple..if so then I'd probably address it to each separately and inform the other you invited them (if you talk to them often that is). So that way if they break up you still get both of them attending..umm although that could be awkward. lol sorry i'm not too helpful..but I'm just putting "and guest" for the majority.

I put both their names to the couples that we know are in a serious relationship. And to the people we know they might be seen someone but it just started or we're not sure of their status we just addressed it to the person we knew more and added a guest on the RSVP card.

We didn;t really have this problem, per se, as all of the couples we invited were living together. However, we did invite a couple, as a couple, and they broke up just prior to the wedding. Originally they were both going to come (she was a BM) but at the last minute she pulled out. If they had both shown up, it may have been akward.

I think it depends - would you invite the guest without the other person? If yes, then unless they're living together, give them separate invites. If you wouldn't invite the "guest" without your friend, write it to both of them by name, but just to the one you're closer to. (Unless you're ok with them bringing someone else if they break up! )

If a couple is dating, the invitation should be written as:

Mr. Friend's Name

Ms. Friend's Girlfriends Name

Address

If you know her better than you know him, then you can swap it.

I sent invitations to whomever I knew better, even if they weren't living together. Why waste an extra invite. Also, I think it's rude to write "and guest" when you can ask the person what their SO's name is.

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.
