My dad passed away 8 months ago. I will have my mum walk me down the aisle and I want her to do the speech as well. However she bought up that my step-dad could walk me down the aisle. When I said no to this she said she’d like him to do the speech so he’s included. I don’t want this as it feels disrespectful to my dad and it’s never been something I wanted. I don’t want it to cause tension between my mum and I. What ways could I include my step-dad that don’t include walking me down the aisle or doing a speech?
