I get the impression that a lot of what's bothering Lobodeb isn't so much whether he did "enough" for this particular birthday, but what he did (or didn't do) for her birthday this year as compared to what he's done in the past. And yes, if I were with someone who used to make a big deal about my birthday and is now making lame excuses for why he couldn't get me anything, I'd wonder what his problem was.
I think that how a significant other treats you at birthdays and other holidays can give you some indication of where you stand with him or her. If your SO is extravagant when buying for himself and cheap when buying something for you, that's not a good sign. If she tosses a tantrum if you forget the anniversary of when you first met, but she can never be bothered to remember your birthday, that's a warning. While my ex-husband and I were dating, he insisted two years in a row on celebrating his birthday by going to lunch with his ex-wife. I definitely should have read that sign!
On the other hand, if you have a generally wonderful SO who doesn't give a flying toot about material things and can't even remember his own birthday, then his failure to make a big deal about your birthday wouldn't be worth fussing about.
