I'm going to tread lightly and I Ask that you all do too (in other words don't make it an A hate session) but I do believe it's clear she felt wronged and used - I've always said L made her feel used once when biding his time before he & N reunited and again to hide the pregnancy last year (while completing the likely NDA obligations).
These songs sound like her way of trying to get out her side while she still has the attention. Regardless, a girl in a happy relationship does not post such content. The best case scenario for A is that they gave in, and she was allowed to be there posting horrible break-up songs. If that feels like a win in her books, so be it.
On a positive note: It’s been > 3 days and L has not liked her post. Let’s get this done ‼️
