Sasuke had already gotten used to it.
It was normal for Sakura to cry for various reasons - out of sadness, happiness, anger or frustration.
He would always then walk up to her, wipe the tears and listen to what she had to say.
Sometimes he tried to comfort her - in his own way, other times he tried to help, and another times he rejoiced with her, just not as emotionally.
Sasuke loved every aspect of Sakura. But the emotional one the most.
Every tear testified to what a wonderful person she was, how much she cared for others. And how much she loved Sasuke.
(And when she smiled, he knew there was no saving him - he had fallen too much in love)
