Long story short, my dad moved 200+ miles away when I was 15 after splitting from my mum. Stayed in contact but was minimal, regular phone calls and the odd visit, no child maintenance was ever paid to my mum. Fast forward 12 years, and he moves back in the area when my DS was nearly two as he had no other real reason to stay he was living and he was missing out on his only grandchild growing up (fair play). Our relationship is amicable but strained, not close. I involve him in our lives so DS knows him as well as he knows other grandparents.
So, we have just set a date for our wedding, which is a small non-traditional wedding, close friends and family attending. Since telling my dad, his partner (who I have known for less than a year) has text to ask if my dad will be giving me away as it would mean the world to him. I (politely) replied that no he wouldn't be, as I didn't want anyone to give me away, I would be walking down the aisle with my DS, and I also don't think it would be fair on my DM as she brought me up for longer. She then replied a couple of times questioning my response and telling my how much it would mean to him.
In the end I made her realise it's my/our day and we are doing it how we want to, which she seemed to accept. However I have now heard nothing from them in a fortnight, except the one word response to my text regarding ceremony/time being confirmed, so I think he is being off with me.
AIBU or is he right to be disappointed??
