How do Helen and Lib get along? Why?

There seems to be a certain amount of jealousy between the women, although I do not find an exact cause. If I do, I will add it below later today.

When they were in the car Randy said, "That was a strange way for Helen to behave. Don't know what's eating her."

"Not at all strange," Dan said. "Just human. She's jealous." "That's ridiculous!"

"No. Helen is a fiercely protective woman-protective of her children. With Mark gone, you and the house are her security and the children's security. She doesn't want to share you and your protection. Matter of self-preservation, not infatuation."
