都习惯了你的冷漠
[dōu xí guàn le nĭ de lĕng mò]
Means 'I'm Used To Your Indifference'. This shows that although the person might dislike their attitude and behavior of someone, who is always apathetic or indifferent towards him/her, but they can only choose to get used to it since they cannot change the situation. This reveals a bit of pain and helplessness, along with acceptance of reality.
