A women firstly do not allow his husband to do second marriage. How a man can do justice between them as he cannot be with all his wives at a time? This woman do not like his husband to have sex with other women.

This is an impossible task to undertake. Its hard enough to keep one happy... and impossible to keep more than one happy.

Obviously your wife is not the traditional wife of your culture and doesn't believe in the old ways as you do. You better go along with her or there will be hell to pay.

What country, what religion?
