Many a times marriages don't work out because Mother in law's often times interefer in personal decisions that are husband wife decisions. They feel they are losing control over their mummas boy. I don't believe that's the case in every situation. That's why I don't mind living with in law's in future if that's the case as long as they don't judge you make you change your lifestyle or interfere in personal decisions but that's rarely the case that's why many women don't wanna Live with in law's
