This song is great! I think the first verse is about him breaking up with her and her reaction to it. "Drowning in her sea" is her tears and emotional reaction. Then the next verse is about how the two of them run in the same social circles so "all the bodies hang on the air" are their friends being nosy about how they'll react to being around each other. But he thinks she's still torn up about the break up. So there's more "drowning in her sea". Then the last verse is about how when he has some distance from the break up he realizes how much he regrets letting her go and in turn his heart is broken. He's a rider burned to the ground.

@skydancer 'Drowning in her sea' could also be a reference to the drama from the relationship and having to deal with it.
