yes fateh has always been like obsessed with jasmine the guy was ready to let go of his family his own ideas and thoughts uproot his entire lifestyle crumble his own identity to please jasmine so i dont think we should be shocked with his present behavior of him not caring about tejo because if the guy could pick a woman he knows nothing about over family who brought up then betraying tejo is really nothing for him
i mean we should not forget the psycho like activities he did when he thought that jass was going to marry his dearest jasso at that point jasmine was not even aware of his existence and he still was so over possessive over her now when she is willingly reciprocating his love ofcourse fateh will cross all boundaries for her
