To think kids should be invited to their Dad's wedding?

[Mummyme1987]

Been divorced awhile kids are teens and see him a few hours each month. They were asked to be bridesmaids when he got engaged last year. They were excited and looking forward to it. But then nothing was said again about a wedding. They asked a few times but were told nothing was planned. Then after seeing a mutual friend one day it was discovered that they had planned a wedding but were excluding the kids. They tried to talk to him about it but he cancelled their contact and refused to answer the phone. They text but he denied it as first then after they said how they knew he said they were getting married abroad. Then the kids see the photos of him getting married locally. Aibu to think this isn't right? They are now saying they don't want to see him again. I'm not sure what to say to them. They are old enough to choose but to never see him again? I think he owes them an apology at least. Aibu to think this?

My dad didnt invite me or my brother to his wedding, we only found out about it after when he apologised about not inviting us. I know it was his wife that didnt want us there as she has alway been honest in her dislike of us. As a result i now see my dad three times a year and it suits us. Apparently the resulting row between her and my grandad about us not being there was fairly spectacular.

I can also see this coming from the dad's wife in the op situation, but never the less, it is not a green light to treat his daughters in such an disgusting way. Op dds are discovering now, where his loyalties lie, and have made the right decision to go NC with their deadbeat dad, and if I were op, I would not be sending the youngest either. What for more of the same!
