Lyric discussion by Coneman 

My take on it is that a girlfriend cheated on him, he was superpissed at her, and now he's saying that this is the only chance she ever had for happiness, and without him she is pointless. The violence is metaphorical, I think.

"don't try to swim to shore because you can't go back" Those lines are probably my favourite in the song. He's saying how she chose to swim out there in the first place, and he is the shore, and she's not coming back to him.
