Where there is love there won't be room for hiding anything from your partner.
Are you sure? Although, I do not see any reason to hide your gambling activities from your wife but when it comes to life generally, there could be a good reason to hide something from your wife. Someone that is receiving a salary of $1000 weekly has a reason he told his wife he is only earning $350 weekly. Or there are people that will not let their wise know how much they are earning.
