It's important that your children know when, and under what circumstances, they will see their father. It's probably too early for an overnight stay right now. Depending how things proceed with you and your husband, that can come later. Also, you can always consult with a child mental health clinician about how to manage your situation. In my clinical practice I see many parents and children to help them through separation and divorce as a way to prevent problems from developing.
Children can survive their parents' divorce, as long as it's managed in a sensible way.
