Thats one sane decision. But I dont understand one thing, why you guys cannt excercise your ownership of house. And its the BIL and wife... who should face the music than you guys. I think You need to just make ur hubby undertsand this. If he doesnot understand , you can always use some of mentioned reasons as sex deprivity. Sometime its good to be manipulative. I am seriously amazed How your BIL can get married, without thinking where will he keep his wife.. Weiterd Indian traditions.. Joint Family.. I think in past people had joint family.. Becos they had too much time at hand to focus on this trivial power tussle. It defiinitely kep MIL, FILs as centre of game... Its better to not be in hollow relations.. then be in some and get disrobbed of peace and mind.. And I really dont get.. this Indian husband's apathy for wife's issues. May god give some wisdom to them.
