Until he ignores her completely it will never end.
The sad reality is that this will never be over, she barged into the Cobraverse and she's here to stay. There is ZERO chance she'll just forget about him: she DESPERATELY wants to lock down a man, she wants to move out of her parents' house without having to lift a finger, and she wants free access to someone's bank account. Bonus points if the guy she's after is a complete pushover like Joshie. Cobes also has the advantage of having eyes on him constantly, so she knows she'll be in the spotlight like she craves all the fucking time. Plus, she knows she can bully him into going live, so she can get brats and vodka forever.
If you think about it, Josh is Jessica's dream partner. Someone who will provide money and housing and not ask for anything in return, someone that can easily be manipulated just by showing off saggy 40-year-old tits or by offering vodka, and someone that absolutely indulges in her freakouts and mind loops. She LOVES to freak out, rage and scream at everything constantly, and Josh just adds fuel to the fire by even engaging in it. Jessica is perfectly comfortable obsessing about Josh until she dies, she will not let up.
The thing is, she has no real power over him. I mean, she just released their """"""""""sex"""""""""" tapes, but she's got to be running low on ammo at this point. She has already called him a sicko, a pedophile, a rapist, an alcoholic, faggot, limp dick, small dick, daddy's boy... she's going to run out of insults eventually.
The reality is that she will NEVER EVER shut up about him, she will never let him go. Not only is she completely BPD, she is a mega narcissist with a broken brain. She doesn't have the mental capacity to understand that Josh broke up with her. It's not that she's deluded or that's she's trying to lie to everyone, it's that she literally doesn't have enough brain function to even comprehend that she's a piece of shit and no one wants her. In her brain, she is always perfect and always the victim. If you try to tell her otherwise, her brain cell just burns out and defaults to calling you a demogorgon bitch, your can't keep your dick hard because your mother didn't suck you off, etc. Her brain is literally broken at this point. It is incapable of reasoning, make logical decisions, or even complete a single thought loop. It's more than just being dumb or retarded, it's simply not functional. Someone with Down syndrome can make more sense, have more jobs and be more productive than Jessica, who cannot spend over 2 minutes without shouting "SLUT" into thin air.
And, lastly, there is always going to be another payfaggot willing to fork over thousands of dollars for this cacodemon to go back to Casper and harass Josh. She has no power over the boy, unless someone books AND pays for her flight, and pays for a hotel and gives her pocket money. Jessica will always be down to go over to Joshie's, and some nigger lover will always be willing to pay for it, especially because Jessica live-streaming Josh's suicide while in selfie mode is really cool content, right guys?
