Should I tell my dad that he hurt me?

I (currently 34f) was raised by my dad after my alcoholic mother left us when I was 12. My dad raised me and my siblings 9m and 1f, and my older half sister 17f who my mother had from a previous marriage. My older sister was pregnant when my mum left and once the baby came she went to live elsewhere because there wasn't space in our small 2-bedroom house.

He sounds like a good guy, and he isn't a bad guy really, he just had no interest in being a single father. He kept us alive and in school, but didn't really provide any support beyond that. He taught us to be tough and to never show emotional weakness. We didn't have much but we were fine.

Last year, we all went to Disney in Orlando with his new (wealthy) wife and her children and grandchildren. They paid for all of it (we're from the UK so it was a big trip). At one point we were waiting for the firework display and everyone got in a family picture done by one of the Disney photographers - except I was in a nearby shop (literally right where they were stood). I was upset when I realised I missed the photo, and my dad said "you couldn't expect us to wait for you."

That sentence has really stuck with me. I realised later that actually, yes, I could have expected them to wait for me. I would have waited for any of them. I also think if it had been his wife or one of her children or grandchildren, he would have waited for them.

I know this sounds like a tiny ridiculous problem. But it felt like it summed up how I've been treated my whole life (and my siblings). I think about it all the time. Should I tell him?
