We still give each other presents, but have long since agreed not to exchange cards.
I think the real issue here is AGREEING about what you do.
I would be very hurt if DH suddenly decided without asking me that I didn't need anything.
To me a present is not necessarily something you need, but is either something you would like to have, or something the giver wants you to have.
Do try to discuss this with each other: being hurt and saying nothing won't solve the problem, and stopping buying anything for DH will either be taken to mean you agree not to give presents, or hurt him.
My DH is at a loss to know what I want (even if I tell him what I would like) he really needs a) to be reminded of the date of my birthday at the beginning of the month, because once we get to the actual day, at the end of the month, he has no, or not enough cash left, b) I have to convince him I really would like such-and-such, and if it is useful rather than pretty or valuable that it is quite all right for him to give me something I have asked for even if it is useful, and in his words "You could just go and buy it".
Does this sound familiar? Men seem to me to entirely miss the point that being given something instead of having to go out and buy it can be a treat in itself!
