I wouldn’t do this. Your wedding isn’t just about you, it’s about you and your FH and the celebration of your marriage. A retirement party is just about the person retiring so it would just be about you. Doesn’t your FH deserve to be celebrated at his wedding too?
Thank you all for your comments; I truly appreciate your insight and opinions. I will take what you all have said and give it serious thought. I haven't begun to plan anything at all so now is the best time to change perspective.
