I think this is what will happen:
anjali will not turn negative; everything will slowly return to normal in raizada house[ this gives PH some time to stabilise the trps too with some romance and possibly, consummation], and then, when they r ready to leave for honeymoon or something, shyam returns and shoots arnav to take revenge on khushi , but khushi will get in the way and get shot.this will shatter arnav to the core, because inspite of wrecking her life, this angel not only gave herself completely to him and loved him selflessly and supported him endlessly, but also risked her life for him,THRICE! he will be heart broken and sad, and take care of her.THAT WILL BE HIS REDEMPTION! there will be no need for a wooing track after that, as he is already wooing her[acc. to me]. but, there will be a remarriage track as he will blurt out to his family[ possibbly in the hospital] that he forced her to marry him for 6 months by threatening to stop payals marriage[ IN ONE OF HIS OUTBURSTS]. anjali will be shocked, and anjali and nani will arrange for a remarriage once khushi gets alright and ask her to stay at the guptas to teach arnav a lesson/ to tease him a bit😉
