You really need to sit down with your husband and find out what is going on, and if he really feels that way. If he truly does not want your kids then you will need to make a decision about what is best for your children.
Go into couples counseling to discuss why he doesn't want children. It may be out of fear of providing for them or worry that he may not be a good father. Or he may be reluctant to have children out of the level of commitment it entails. Talk to a professional together.
If you suspect your husband feels this way then get yourself out of this situation as soon as possible. You don't want to put your kids in harm's way. Move out and have him relinquish his parental rights and look after your kids yourself with help from your family
