To WitchDr: not taking this girl in ma mind, but i swear i would prefer living in a joint family system, i would love to call my mother in law, as my mother, his siblings would be my siblings, so what if she scolds me, she IS my mother as she is my husbands mother. ye dil ki baat hoti hay, agar mujhay apnay husband se saccha piyar hoga to uske tamaam rishto se bhi automatically sachha piyar hoga!!! main kabhi seperate house main nahin rehna chahun, ghar main buzrug hotay hain to sukun hota hay, jab ghar main jannat hi naa hoto ghar jahannum ban jata hay!!! I swear upon Allah this is what i think!!!
Just out of interest, are you married? To do the above you would need a lot of patience, respect for others including not back-biting and to be a sort of 'peace-keeper' in the home.
You appear to hate this girl so much that it almost makes me feel sorry for the girl! You just can't expect everyone to agree with you and hate this girl with you, cos' we all have different views and we have heard just one side. Ok, so he is your cousin and you care for him - but you have taken on all their problems as your own.
