I will try and explain that statement in a satisfactory way... an "inconsiderate" individual is someone who should be aware of their partner's thoughts and feelings because their partner has gone to the effort of explaining these things and stressing their importance.
It is not possible for another person to be aware of your feelings. Only you have direct and accurate cognition of your feelings, emotions, thoughts and perception of external stimuli. All anyone can else can do is make a prediction based on various pieces of information, and than attempt to have empathy and/or understand and relate to that state.

There is no way for my GF to know that I am currently thinking about region and culture of the region of Waziristan/South Afghanistan at this moment, and I can't make a realistic demand or expectation that she could/does, as an example of the limitations one should place on that sort of thing.
. Yet said individual chooses not to consider this information when making decisions that ultimately affect both partners. Such disregard for partnership equality is, in my opinion, the "rude" part.
Perhaps that is not in of it self a "bad" thing. Consider "double effect" briefly, is an argument that An act which was intended to do good, or at least a neutral thing, which also causes a bad thing, is not bad if the bad effect was neither an ends to itself, or the means to effect the good effect, and where the good outweighs, or at least matches, the bad.
Reactor meltdowns Japan, and related damages. The reactors where built with the purpose making heat to boil water to spin turbines to make electricity. A not "bad" goal. The fact that they ended up causing a bad effect can not be held against them, as the contamination of the area was not the ends sought by building them, nor was it the means to carry out that end.
So he may make a decision to do something that benefits him, that may/does end up causing you some suffering, but for which causing you that suffering was not a goal, and the act of causing you suffering was not as such part of achieving the other goal. It is essentially a side effect, and may merit some level of understanding and/or forgiveness on such basis.
(Alternately, doing what would of pleased you, may of caused him suffering, and it becomes a catch-22 of who shall give up something they want to enable someone else to have what they want?)
But I'm fishing here cause I am still working with very abstract concepts.
