Former husband

I always enter people in the tree view. Click Tree in the top. Click on yourself and at the bottom, click to add a Spouse.

For adding children, if you had an ex and a current husband, click your ex and add the children to him. The program will automatically know you are the mother.

If the children are added incorrectly, to change relationships, click on the profile that you want to change and then click Edit at the bottom. Go to the Relationships tab and you can change the parents.
