To spell my husbands name correctly.

[Burlea]

In the last 5/6 years when my DB and SIL send DH a Birthday card or us a Christmas/Anniversary card, they have spelt his name wrong ( his ends in 2 Ns,they only put 1).
I have told them a number of times and their reply his that one of their friends spells theirs with only one N. We don't live close so only see about once a year but and it's a big but they have know DH for over 40 years.
DH has now sent a birthday card to SIL (1/9/2018) with his name highlighted with bright yellow marker pen yet it is our wedding anniversary today and the card has come with his name spelt wrong. DH hasn't seen this card yet. I think I'll bin it as I don't want anything spoiling our day.
DB is my older brother and I don't want to fall out with him. But I feel as though they are disrespectful to DH.

DH has just pointed out that my Dad uses a different spelling of my name. I can’t recall ever having noticed. I am thinking of changing to it.

Don’t dwell.

I'm with you OP, it'd annoy me too. Mind you I am probably over-cautious about spelling names correctly - I know a Nicky, Nikki, Nicki, Niki and Nickie, and am forever checking I've got the right spelling 😬

I'm sure if your DH gets creative he can come up with alternative spellings to your DB and SIL's names!

My aunt has spelled my surname wrong on every card she's ever sent me - she's only known me my whole life! It doesn't bother me at all, it's the thought that counts.

Sending them a card with his name highlighted I would consider very rude. I can't believe you would let a card ruin your anniversary though, especially from people you don't see very often.
