Here is some background first: I have a good friend of mine from high school who is engaged to this great guy. They moved out of state a little while back, and since then, I heard that this friend's fiance got a great job offer in another city on the other side of the country. My friend couldn't move with him because she is currently attending grad school in this other city. So they are doing long distance.
Or so I thought. As far as I know from my friend, this is the current situation, as she has said nothing more to me about her situation with her fiance. Well, come to find out from one of our mutual friends living in the same city as her, apparently she broke off her engagement with her fiance but is still dating him. but she is also dating SOMEONE ELSE in the city! Keep in mind, she hasn't told me any of this. So when it comes time to do invitations, who should I be inviting with her? ex-Fiance-but-is-still-"dating"-him? City fling? No one? I am confused and I don't want to be rude. Any suggestions would help.
