It was my mums birthday yesterday. On Tuesday I ordered a card online, signed from my, DH and our DC, which was posted first class so I was expecting it to get to my mum at some point on Thursday.
On Thursday (yesterday) I tried to call her in the morning to say happy birthday but we kept missing each other's calls (work) so ended up texting her happy birthday. This morning I texted her asking if she'd received our card, she said no and also said she was extremely disappointed that my DH didn't text her yesterday to say happy birthday??!!!!? And then did the "oh never mind" guilt trip. I said the card was signed from all of us and was hoping it would have been there by now and no idea why he'd need to send a text to his MIL when he already sent a card? Or AIBU and he should have text her? They're not particularly close if that helps.
I text my mums new husband on his birthday but have never sent him a card.
