my friend's jealousy is absolutely unhinged

so whenever i'm having fun laughing with someone else, she gets this look on her face. just dark energy. then she comes over and grabs my hand and stares at me. won't say anything. but then on the way home she's like "oh you're close with that dog now? when did that happen?" and she's just attached to my side trying to change the subject. brings up some random old thing like "remember that one time? that was funny right?" and then she gets all moody outside my house being jealous and complaining about being jealous. like bestie I HATE that you're jealous but also??? you're literally the one doing it???
