My father is primarily paying for the wedding, but my fiance and I agree that we should include all our parents on our invitation. The line for his parents is easy, Mr. Jon Doe and Mrs. Jane Doe. My parents are complicated, I have a father, a step-father, and no mother since she passed away 5 years ago. How do we do this without my family looking completely dysfunctional next to his nuclear family? And how can I make it clear that my step-father and father aren't a gay couple? My step-father means a lot to me, and I know he would be tickled pink to see his name on the invitation. I'm not sure I want my mom's name on, since she's obviously not going to be there and isn't a host. Any ideas?
