I'm Baffled by the Concept of the New Song, "Medicine," by Queen Naija

On the radio I've been hearing a new song titled, "Medicine," by a singer named Queen Naija. It has a catchy sound, but the whole concept of the song is moronic. Basically, she knows the man she is with has been cheating on her with numerous women, which makes her angry (normal concept for a song so far), so she gets revenge by...sleeping with a bunch of guys he knows in order to then tell him about it for no reason other than revenge--wait, what? Seriously, of all the reasons to have sex the idea she is doing it to, "Give you a taste of your own medicine," is one of the worst excuses I have ever heard. We as humans have sex for fun, to relax, and of course if we feel horny, but just to make your spouse angry? I ain't buying it, she's having sex because she wanted to have sex and her man being a scoundrel just serves as a handy excuse, I'd say.

Plus, if this really is a case of just boning a bunch of dudes to make your man, "Cry," how unhealthy a relationship is that where all you do is cheat on each other to cause the other to hurt? Apparently the song draws from a former marriage Naija was in, so thank God they got divorced if this song reflects what their relationship was like. I get the idea of the song, that she feels slighted, but I'd get the concept more if that meant she then went and slept with some former lover or someone she has been fighting feelings for, etc. Instead it is just like, "I'm gonna call up all these guys to spite you!" I just find it baffling, and it results in a pretty weak basis for a song, methinks.
