14yo ds, strong Asperger traits (no assessment or diagnosis) frequently behaves to his siblings in a way that I see as nasty, but he sees as reasonable. When challenged "Would you treat your friends this way?" or similar, he generally responds with something along the lines of "I make an effort for people who matter to me." He's quite up front that family doesn't matter, he doesn't care about us.
Yet he loves us, just doesn't see why he should make any effort to behave in a socially acceptable manner with us if he doesn't feel like doing so.
I feel like I'm banging my head against a brick wall.
