1) My step-mother is in a long-term relationship (divorced from father but we are still close), do I include her boyfriend on her invite and send it to her house (they live separately)? Or do I send them each separate invitations? I am an idiot when it comes to wedding planning. 2) Also, another guest has a long-term relationship (I am friends with both) and she lives with her boyfriend half of the week (she works and has an apartment in another city). Do I send them a joint invitation, or separately? 3) And thirdly, my future nephew is 18 and is in a relationship. He lives at home. His girlfriend was not true to him, and they broke up. They have since gotten back together, and his girlfriend is not allowed in his mother's house. Do I invite her? I don't want to cause drama at my wedding, and it seems like no matter what I do, I will be upsetting someone else. My FI thinks we should not invite his girlfriend to save money. I know everyone over 18 should get an SO. What would you do?
