Tariq Amin may be feminine but he's not gay- he's married with kids. Just because someone's a stylist or in fashion industry, people automatically assume he's gay.
HSY is gay/bi. That Sheikh Amer Hasan guy was gay.
That's his social cover. He probably wasn't open enough to accept it publicly. Her wife can tag along if she wants to live the life maybe 0.005% of Pakistan lives, attend the elite parties, meet famous people, etc etc. Kind of like Sharukh Khan or Kobe Bryant's wives. They want to keep living the life, they accept their husbands' other life (they are not gay, but who would be stupid enough to believe that they don't "party" with other women) and go along with it.
