I have not been in Pakistan, but how about a White Marriage? A White Marriage is a covered marriage of fake straight couples (or pretending straight couples), between a gay man and a lesbian woman who use it as a cover for their private freedom. It is a nice way to be able to live the gay life you want, but also keep your clueless family happy. Your lesbian wife will only cover you and you will only cover her, and nothing more. No shared life, no shared family plans. Just a marriage-cover.
In Greece, where homosexuality is legal and protected by the laws and constitution, sexual discrimination against gays is strictly prohibited. But even so, laws do not stop homophobia from existing in parts of the society, especially in distant, rural areas. Gays who happen to be living in small villages where societies are more conservative, often hide their sexual orientation from their parents, and an option is to move to bigger cities where life is liberal. However, for those who could not want for whatever reason, to move from their villages to cities, always have the option to seek a White Marriage, (aka find a Lesbian and make a covet marriage). This works well, and the ads for it can be found in newspapers or on internet.
I don't know how well the things in Pakistan, but perhaps you could try a White Marriage with a Pakistani Lesbian woman? However, this means your parents will have to accept and welcome a completely unknown woman in their family that is not a cousin to you, especially if your family has no lesbian women available for you in it.
