This seems a forced story - Chloe's apparent need of a shrink to deal with the pregnancy that didn't happen. It's not as if she wasn't fully aware she likely couldn't even get pregnant and then carry a child.
What's this big deal about not being able to communicate her feelings w/Dan? And so what he's a father now - to a married woman!
Why are Chloe, and now Nicole so worried about Chloe's having to hang onto her man?
I just can't find much substance to this.
