AIBU to feel hurt by mum’s brief reply on Mother’s Day?

[NotOneMore]

Hi. How would you feel if this was your exchange with DM? For context, every month I send my parents money, same amount (more on birthdays and Christmas) on the same day, because they need financial support. I have not seen them since 2019 due to COVID and now war, but they have always been in a safe part and chose not to relocate to me in the UK. The relationship has been a mixed bag, mainly to my father being an arsehole his whole life and her choosing him every time.

Me: Happy Mother’s Day! Thank you for everything you have done for us. wishing you health and peace. Also, sent the transfer as usual, code to collect 123.

DM: I will collect tomorrow, thank you very much.

I don’t care about the money part, but I sort of felt rejected with the greeting, I tend to show more appreciative response to my DD. AIBU?

Her reply is really thoughtless. It's always sad to be taken for granted.

That's a very business like reply, I'd be disappointed.

My mother in law sent me a lovely message this morning and I sent a lovely one to a family member. They were full of love and warmth.
I feel really upset for you.

That message is awful. It sounds like you have always had a tough time with your parents. It’s very hard to have a healthy relationship with people like you describe. You didn’t deserve that message and I hope you manage to put it to one side and enjoy your day.

Playing devils advocate here, is it Mothers Day in the country that your parents live in? If not, maybe it just caught her off guard (I think it’s May in many places) If it is MD there then sorry, her response was very dismissive

Yanbu... sorry op, sounds very hurtful.

Mother’s Day is different in different countries.

my brother sends my mum flowers on New Zealand’s Mother’s Day which is not today.

also, are you saying their country is actually at war just that they are in one of the “safe” bits?

Other parts of the world mother's day is May, not today, so perhaps they don't understand as it isn't mother's day where they are?

I get mother's day flowers from my son in Canada in May as that is when they celebrate it.

They are in a small row in west of Ukraine. I know it’s not been easy for them but they refused any help other than financial.

Mothers’ day was not a thing there when I left in early 2000s, so for years I have wished this to her on the UK date. The response has been mixed but this is a new level.

Sounds like Mother’s Day doesn’t really have any meaning or importance to her but that the money does (I don’t mean that in a bad way, just that maybe they need the money).
