I think Danielle has a very innapropriate relationship with her daughters. What good mother lets a man into her children's lives that she hasn't known for a very long time? She even says about the dating and the sex and stuff "they're big girls" um, they are 14 and 10. That's not "big girls."
I don't think she's thinking about her daughters at all in her dating life. She's not looking for a man who's parent material, she's not being cautious because of her daughters, she is thinking merely about what is good for her, which is a man with money. Lots and lots of money.
I think she has crossed the line between friend/mother and friend. She loves them, yes, and cares about them, but she isn't being a mother to them, she's not being an adult. And that's what really upsets me about her.
BTW, is Teresa married to anyone in the "family" or is she just really close to them?? And Jacqueline is married to the brother of the two brothers that Caroline and Dina married or to their brother?
