I don't see Vienna ending this under any circumstances (well, that is unless she gets offered a high-paying job in the media, like Melissa, the chances of which are probably non-existent). Whether she is truly in love with him, just infatuated, or caught up in "winning", being with Jake offers her the best options right now. Otherwise she'd have to go back to FL and try to embark on some mundane career, which I don't think she has the slightest interest in. If she starts getting bored with him once they move back to Texas and his media opportunities dry up, I can picture her just acting out, going out partying with friends or possibly cheating, and treating Jake like a poor unsuspecting and easily manipulated patsy/Daddy. It will be up to Jake to throw her out if it gets to that point. Or she may surprise us all and actually grow up. Time will tell.
