the song seems to me like a troubled relationship!! when the girl was fully devoted to him, he acted like a jerk, egoistic!! but now she'd had enough now she has left him, he realizes her worth and his mistakes but its too late!! A lesson she taught him!! so now he is regretting but now he is changed!! life teaches lessons in a cruel way!! but life always have happy endings!!
