My theory is she preys on Simple Nate when he can provide something she wants (like access to a Poly Villa) or probably cash.And yeah if she is living halfway across the country with somebody else why is she posting that Merry Christmas pic with him at the end of 2020? That makes zero sense.
He should give her the dog, block her number, and do his best Justin Scarred impression by finding a female fan (that respects + looks up to him) and meet up with her and never look back at that self-centered narcissist Veronica.
