Apologies in advance if I'm missing a post about this topic already.
I don't follow them closely, so my understanding is that Lily Allen (British singer) and David Harbour (American actor) split up last year with rumors of infidelity reported in the media. Lily Allen just released a new album last week, West End Girl, and OMG the lyrics/details!
Depending on where you are in your SI journey, the songs might be triggering or cathartic, but here's a sample:
I know none of this is your fault, messaging you feels kind of assaultive
Saw your text, that's how I found out, tell me the truth and his motives
I can't trust anything that comes out of his mouth
No, I can't trust anything that comes out of his mouth
How long has it been going on? Is it just sex or is there emotion?
He told me it would stay in hotel rooms, never be out in the open
Why would I trust anything that comes out of his mouth?
Oh, why would I trust anything that comes out of his mouth? -Madeleine
I'm far enough a long now at this point that it doesn't hurt and I don't start ruminating, but man, I remember those early days (years, really) and how much this resonates.
I will say though, that a brief read up on Lily Allen informed me that she cheated on her previous husband at least 2x, so I do find it slightly ironic for a (former?) cheater to put together an album from a betrayed POV. Cheating sucks...
