I think its similar to what Scottboy79 said:
"Maybe it's about somebody falling apart, while their ex-lover, or soon-to-be ex-lover, watches them wilt away with the perspective of sheer joy, thus the author chooses to leave the subject, resulting in the author feeling better about themself as a result. Getting ahead while the "getting is good"."
It's about watching someone else falling apart, but I wouldn't say the author feels better about themselves, more they don't care anymore. I think the author has put up with so much from the other party, and now that their falling apart, they just say ''fuck you, it serves you right''
