Its about khloe. He says that he was in love with someone that would say mean things to him. He wasnt good enough, but was good enough for her to spend money on her (even though she has her own) when he sees that he makes someone happy with buying things like $1000 bottles of alcohol and Large bank on jewelery, one likes to think thats what someone really wants. The not enough was that liquor and jewelry are not enough. That person wants more than that. Maybe he thought buying her material things would make an impression. She has her own money. She wants the inner post malone not the one that buys alcohol and jewelery. He may have just wanted her for clout or popularity. When a man gets shot down, there goes his ego especially with a woman of high status. No matter what, she should never had told him things to hurt him. The line that stood out really hard was "devil in the form of a whore". That line is a statement that i dont know if people understand but when he says that, hes saying that hes attracted to whores. The deeper meaning is that post malone knows the devil knows that post malone likes to delight in whores and he used that for post malone to get trapped into. Its not that in unfortunate events he gets the wrong girl cuz they sleep around.
