THINK...
he never tolerated anyone insulting her (remember how he spoke to those women who came to give blessings to the newly wed bride) ,
he was always protective and possesive towards her(diwali- when an unknown man was trying to dance with her,,he became very angry and possesive)
he doesn't even bear anyone looking at her (Nk looking at her loosen outfit)
he cannot see her tears,, he would go beyond his principles to make her happy (saying sorry)
he always cares of her public reputation (Heer-Ranjha)
he is not ready to accept any insult towards his in-laws (Does recent GH track prove that although he is not ready to forgive her and make her his wife, but he has already believes in the relationship that he has become the son in law of GH?)
He couldn't stand the groom's party insulting his in laws and their kith and kin.
IT SEEMS,,
HE may be believing in his words..but something (MU) drags him back and prevent him from practicing this preach..he is repenting time to time as he is not able to put this in to practice,,,as if it reflects ---if there had been no MU, he would have easily practiced this preach..
On the other hand , this may be the scars of his old wound,, what he wished his brother in law would be,, what he wished every husband would be ,after undergoing the unbearable sorrow of mishap with his only world- Anjali di & Kushi
If there comes a day he realizes his MU, then ther will be no hurdles or boundaries for him to show how to respect her ( and her family),but alas!! till he cleares this MU his heart will keep fighting over the practice and preach.
All these are because of love,, hate is also playing one aspect of this love-- embraced with jealousy of not letting anyone owe which he believes is his!! He behaves with her in his own manner,, sometimes rough and hard on her, one may say it is insolent or rude,, but seems it is also ASR style of showing his concern and love. He shouts on her because he loves her, but he himself is not ready to accept it sometimes,, SO, ISN'T THIS LOVE??
Even he knows (due to MU) what sort of a destrution his wife has created , what sort of face he is believing she has, he still can't stop himself caring and being softened towards her, and even tries to give life to her dreams...That is what he wishes ,but when he faces the bitter truth, the prince turns to be a beast.
He tries his best to avoid disrespecting her, see how he asks her to come out, instead of talking about the theft of his vehicle's spare parts.
It's not what I mean : that she is totally innocent and not desereve to be treated in this harsh manner,, but yet from his angle he is desperate as much as she is!!
Remeber his own wors (Heer -Ranjha)
He says THERE IS SOME OTHER WORLD WHERE THEY CAN BE UNITED.
Isn't this what he always wishes??
ISN'T THIS HIS DREAM WORLD, WHICH HE LONGS TO LIVE IN??
