My fiance's dad left them when he was still a baby. His dad won't be invited to the wedding. We want to find a way to honor the "father figure" in his life as well as his wife, who was like a second mother. He lived with them for a few years and is probably just as close to them as he is to his own mom. We had thought about having them as "Honorary Parents of the Groom" in the wedding program and walking down separately after the grandmothers during the ceremony, but we weren't sure if that would sound funny, and we also don't want to hurt his mom's feelings or make it seem like she is less important than they are. Help!
