My post was in response to people guilting OP for feeling disappointed, IMO a card is the very bare minimum of birthday celebrations, if zero effort is going into it from her husband on anything else then a card is the very least he can do, it is all OP actually wanted, and he 'didn't get round to writing them out'.
There are people on here telling OP it is just a day and she is ridiculous for expecting anything or wanting to celebrate it in any way!! So if you get absolutely nothing on your birthday from your DH, no presents, no flowers, no consideration, no weekend away, no holiday, no effort whatsoever and not even the bare minimum of a card, and he arranges to be out the whole day from morning till night without asking you then yes, I feel sorry for those people who's relationship bars are so low that their DH just treats their birthday like any other day and disregards them completely.. I'm not bashing them, but they certainly have no right to tell OP she is 'wrong' for wanting more than that.
You have a MUTUALLY agreed holiday, instead of gifts and cards, as your celebrations.. so isn't even remotely related to what OP is upset about, you may not 'give a crap' about cards, but the point you are missing is that OP DOES GIVE A CRAP! All she wanted in fact, was a card from DH and baby and to spend a low key evening with her husband and he couldn't even be bothered.
People should stop telling her she's ridiculous for feeling disappointed.
