Is she right & will she be happy if she leaves?

A friend of ours wants to leave her husband after 14 years of marriage. There is nothing wrongs in her married life & she loves her hubby but her husband has been unable to provide for her sufficiently even though he has tried all his efforts. She is always tense how to pay bills, pay for her kids education, house rent, monthly expenses & ......She feels her life has gone just thinking about donyah & she did nothing for her deen.She has always been the one supporting the family in very hard ways. What should she do? She feels there is no way out for them nothing will change her life as half of her life is gone.
