Like everyone said, withdraw 5k and take your girl on a trip (a present for both you and her/forget the car you dummy). Save a couple grand for future reloads or future presents. Play with the rest more conservatively (even 5-10% a game).
With your style of play, this is likely a once in a lifetime run that you'll spend forever chasing so don't take it for granted. And I don't mean that like an asshole because I hope you can mimic this run over and over again, but that's just the way it most likely is.
