Should I express my disappointment?

My youngest grown son has slowly become more distant from us, even though he lives close by. Of course during covid we barely saw each other, and since then he has become engaged to a lovely girl.

I realize he is wrapped up in his fiancee, and she seems close to her family. I saw photos online that they were both with her family for her younger brothers graduation this weekend (on Saturday).

My MIl law died a year ago, and there was a ceremony to dedicate plaques along the sea-wall for all those that died this past year. The ceremony was on Sunday evening, and I did send a reminder to both sons the week before. Youngest son did not come. I had told the boys not to miss work over the ceremony (we did have a small funeral last year), this was a public service in a park for all citizens in our community who wanted a plaque on the sea-wall. Our other son and family, including granchildren came.

DH was hurt that DS didn't come, and I admit that I am as well. Do I say anything? I don't want to be one of those mums that are always saying 'you never come to see us anymore', but I think this was important to show support to his dad.

your thoughts?
