obligation of a husband towards his wife and kids

i too think she took a very rash n emotional decision tht can lead to harsh consequences.lets think this way wats more imp money or ur relation with ur spouse.wat if he leaves her over this one thing.wat security she or her kids hav then n the family will still get the money.so win ur battle with strategy n not lose it with emotions.she should appologize him n return the money back to their joint.unless she wants to leave him for the money
