Hi, this is a sad state of affairs but you are not alone. You are the childrens mother and carer. They need you around. The service your provide is valuable and your soon to be ex would have to provide that himself (nanny etc which would be costly) or be the care giver. You have rights and he would have to help you provide for the children. After 6 years you have earned 'a share' in the house, after all you forgo your right to work to be a full time mother. Do not do anything without contacting CAB first and getting some advice. You may also be entitled to free legal advice. Good Luck.
