Rolling in the Deep

[There's a fire starting in my heart Reaching a fever pitch, it's bringing me out the dark Finally I can see you crystal clear]

She's been trough a relationship with a sociopath. For her it was like a roller-coaster she didn't really understand, but now that it stopped she has time to reflect on it. And as it dawns to her just how much he manipulated her, anger grows in her heart.

[Go 'head and sell me out and I'll lay your shit bare See how I leave with every piece of you Don't underestimate the things that I will do]

Now that she understands him, she knows how unpredictable he can be and doesn't know what to expect from such a person, but warns him to back off; 'cause she'll knows who he is now, and won't fall for his tricks anymore.

[The scars of your love remind me of us They keep me thinking that we almost had it all]

A sociopath typically lures in his bait by being super-nice. He acted as the perfect man, promising a perfect relationship. Once he had her hooked, he slowly and gradually turned into a nightmare. But somehow she still has problems distinguishing who he really is, from the ideal image he posed to be. Or at least, she still associates him with that.

[The scars of your love they leave me breathless I can't help feeling We could have had it all]

Even though she sees him "crystal clear" as a fraud now, she is still bitter because she knows that he was perfectly capable of giving her this perfect relationship. However he just choose not to, for whatever sinister reasons he had.

[Rolling in the deep] I'm not so sure about this part. In my opinion though, it's a reference to the relationship they had. The verb "rolling" associates, getting down and dirty, getting all into it. And that's what they both did. She got down and dirty by naively trusting him and allowing him to "hold her heart in his hand". And he got down and dirty, by indulging his sociopathic games, playing with her feelings out of boredom, without any sense of remorse or guilt or care for her pain. this is

[You had my heart inside of your hands And you played it To the beat] He controlled her by playing into her needs. The beat means the beat of her heart. He knew the rhythm she swayed by, and manipulated her by this insight. People tend to think that sociopaths manipulate others by fear, intimidation and deterrence. But in fact the most common form of manipulation by sociopaths is playing into people's sense of empathy. He controlled her by controlling her heart, by making her feel guilty and so on...

[Baby I have no story to be told] I have no desire of making whatever happened between us public (yet).

[But I've heard one of you And I'm gonna make your head burn] But if you don't back of I'll expose you.

[Think of me in the depths of your despair Making a home down there 'Cause mine sure won't be shared]

You'll get what's coming to you, (be it here or in the hereafter) so prepare yourself 'cause I won't bail you out.

[Throw your soul through every open door Count your blessings to find what you look for] Try to save yourself before it's to late for you.

[Turned my sorrow into treasured gold You pay me back in kind and reap just what you sow] You enjoyed manipulating for entertainment. But you yet fail to understand just how cold, loveless and meaningless your life is.
