I'm recently engaged and picking my wedding party. My problem is that one of my exes who loves my fiance, happens to be one of my best friends. Because of our history together, I have not asked him to be a part of my wedding party but I have included some other of my male friends to be on my side. I feel terrible considering he is my best friend, yet I feel like it would be unfair for my fiance to include him. He is helping me plan, plus arriving early to be a part of the "unofficial wedding party." I have not had a conversation about this with him, is there anything that I can do?
