What does sorry mean?

What am I suppose to do? What am I suppose to say? Am I suppose to forgive all? Act like nothing happened? And that nothing has changed? You broke my heart I could have loved you But I don’t know if I feel the same Your so fucking special But I have changed I don’t want to care about you I don’t want to talk to you Because it will happen again I wish I could tell you to go And leave me the fuck alone It would be so simple If we weren’t so complicated Why did it go so far If all you wanted was a fuck You only had to say please Instead you told a white lie To put my mind at ease But your back saying sorry Yet again Its easy to say sorry But do you know what it means?
