Re: Really screwed now....
Tell her in your tribe ( back in Pakistan) 1st wife always comes from family, 2nd or 3rd can be from different communities, adding to this, tell her a story about the girl you liked back home and how happy both of you are, and now close to getting married as the elders are looking forward to marry you.
Also tell her, that Pakistani Women don't allow their husbands to have multiple wives ( as they think one is enough to torture you) if anyone dares, he pays the price.
