How do I invite SOs? As in, do they get a separate invite or do they get invited together? Married couples obviously get one invitation, and I assume engaged couples do, but what about dating couples? It would seem weird to me to invite a couple who recently started dating or who are showing all the signs of an imminent break up as one social unit, but it also seems incredibly rude to simply not invite the SO just because I don't know him/her as well. I can't just invite one of them "plus one", so how do I invite the SO without making it awkward if they break up? This probably wouldn't even occur to me, but this happened to a friend of mine recently. They invited a friend and his gf and it was awkward because they broke up after the invitation was already sent with both their names.
