What to write in'MIL' bday card

[helpmewriter]

I've been dating my bf for 3 months.
Met his mum once. It's her birthday. What do I write in the card that's appropriate?
Just happy birthday?
Please help.

Of course - just her name, Happy Birthday and your name.

Why would you need to write anything else?

In fact, do you even need to give her a card after only 3 months & meeting her once?

Are you seeing her on her birthday? I’m not sure I’d even be sending a card if not!

But anyway, keep it very generic - wishing you a very happy birthday, hope you have a lovely day, love X.

Seems a bit much to be giving her a card, you've only been together three months so she's nothing in law to you- she's your new boyfriend's mum

Please. She's not your MIL whether you use inverted Commas or not. She's your very new BF's mum.

Why on earth do people do this?! Formalise relationships hastily and unnaturally?

Calm down. Buy a card. Write happy birthday from Helpme and that's it.

Yes, I'm seeing on in her birthday.
I need to write something generic but I don't know what to write as the card already says happy birthday on it.
If I'm spending her birthday with her, isn't it a bit off to say I hope she has a great day?
Arghhhh

She's invited me to her birthday dinner. I want to be polite and give a card.
It's a card, not a ring. I don't see it as formalising anything.

Dear BF's mum

[happy birthday]

Hope you have a lovely day

Dear Jean,
Looking forward to celebrating your special day with you.

Hope you have a lovely day

Thank you, everyone.

If I am seeing someone on their birthday I write something like "so happy to celebrate your birthday with you" or "thank you for inviting (maybe including given short time frame) me in your celebrations". But I think it would also be fine to simply write dear MiL and love from Helpme and that won't cause any upset.
I am thankful that I met my DH whilst we were still quite young so we weren't expected to behave like proper grown ups. I would definitely have overthought all this etiquette too.

I assumed the OP is young though because by the time you are older things like this are just common sense.

When I was young I would have panicked & over thought things like this.

Yes, you might be right. I think I did expect to be a bit wiser by my age. Still overthink too much And actually I remember taking a box of chocolates over to my MiL’s the night we got together as a thank you for hosting me. Which is a bit naff on reflection. We were both back from uni and living at our parents’ which was a tricky way to start a relationship. Luckily rents were an awful lot cheaper then and we rent yet a nice flat with friends very quickly.
