I’m a big fan of halsey’s music and their meanings but not too invested in her personal life but this song got me thinking, especially with the part “did you know the father’s dna stays inside the mother for 7 years”

So my question maybe an obvious answer to everyone here but bear with me. Is she talking about Alev aydin? Or is she referring to whoever the father was to the miscarriage she had way back

Just curious.
