My dad is 65, divorced from my mum and being seeing a lovely Filipino lady for the past 3 years. She is only a little younger than him and he is pretty smitten and I am all in all pretty happy for them. I have certain worries and reservations that I never express, as I just want him to be happy and don't feel it's my place to do so. My dad has Aspergers and more often than not, does or says things that can be pretty egocentric and hurtful but I try to let things go as much as possible. However, today he informed me that he had been talking about bridesmaids for his up and coming wedding, and I thought I heard him say that he was thinking of asking one of my daughters to be a bridesmaid. My response was that "my little girl would be honoured and thank you for asking her". He went quiet and said " no, you have misunderstood me, I am thinking of asking one of my sisters grandaughters who we see quite regularly to be our bridesmaid" 
. Now, I would say that I see my dad with my 3 children at least once a month if not more, so was just a little hurt but never said anything has it is their decision and I want them to have who they feel is the most appropriate. However, now I feel that o don't want to take my kids with me to the wedding as I think my little girl will be hurt to see another girl dressed up as a bridesmaid for her grandad. I'm just not sure what to do, as I don't want to cause friction before the wedding but can't help feeling pretty
