No, and I didn't mean to imply that. On the other hand, by that argument, if you are whining and unsatisfied because one extravagant gift wasn't repeated ... doesn't that mean you are putting conditions on *HOW* they express their passion? You are judging the quality of their emotion -- how much it's "worth" --based on how closely it hews to your expectations.
Many people who may not be bankrupt of passion and affection may be very nearly bankrupt of the courage to express it openly and freely because of their personality/history/etc; they may have to go to emotional extremes to give the "expensive gift". The latter does not necessarily imply the former.
I will freely admit that this can really suck for their partners. Gestures that have meaning for us will always seem the most precious. And I agree, ultimately that is entirely within our partner's control, to stretch and give or hoard and pull away. A healthy generous person will choose to give, true. But this is still, as you said, properly within THEIR control. To *expect* certain specific "gifts" regularly because we received them once still seems asinine, and at best will probably result in duty gifts grudgingly bestowed, or none at all.
