Mum being overly nice to exes family?

[Beckafett]

Totally open for any bashing I get.
My mum, bless her, is a card/gift person. It brings her happiness and I usually love that about her.
However, when me and my ex husband split (came as a total shock to me but we moved to amicable as soon as we could) some of his family just ignored it and we've never been close since which I think is normal and I'm happy with that.
Please note the only time my mum met this family was at my wedding.
One of those family members has recently had a celebration and my mum wants to send a card and a gift; I was going to send a card maybe but out of obligation more then anything via someone else as I have no direct contact.
My mum is cross that I'm 'stopping her' sending something.
I feel awful and I've gone and picked a gift today.
AIBU?

If they were close prior to the divorce, I would think it wouldn't be a big deal. But if they only met once?? Yeah, it would be weird.

Thank you, I don't know why I needed someone who doesn't know me to say that but I did

You do not mention if you have any children with your ex. If you do, then I think your DM is just acknowledging that the relationship cannot be completely severed until the children are grown up. You say that giving gifts makes your DM happy. I think you are being unreasonable to stop her sending a card and gift to whoever she wants to.

Why does your mum want or need to send a gift, OP, and why does her wish trump your desire to primarily sever ties?

Has she put emotional pressure on you?
