I don't know whether to deal with this matter?
we have married for 15 years.we have a son.
since I suffered mental illness,she has
lived seperately away from me and my son.
I fed the family before,now she feeds it.
she changed her character into a rude
women from a tender lady.she often turns
her back on me and seldom gives enough
money for this family.her temper worsened
because of the pressure on her shoulder.
she who used to be tender often calls
my names and shouts like tigeress.I
don't want to lead this kind of life.
because I am a man whose deadline is
never bear the wife who hurts his
dignity.In order to maintain my son's
interest,I gave up the idea of divorce.
but life is quite long.where is the
end of tennel.so what should I do?
