I watched the entire show, i am not gonna pass any judgement here. You all can watch it yourself and understand things and judge what's right and wrong. I liked the concept of showing of women's desires , specially after marriage. But a woman should only get married if she is sure that she will have kids and take care of them. Desires are apart and responsibilities are apart. When chasing your desires, sometimes you forget to fulfill your responsibilities. Like Billie forgetting to look after her children at night. The show shows two incidents where she forgets about her kids. I won't talk about husband, caz he is just another man. But forgetting your kids is not a good sign of being a mother. If you want your desires and a settling life along ,then may b just don't bother to have kids. So here when she says she want it all... Clearly she is not having it all..when going to her boyfriend for sex she is forgetting her kids and failing as a mother. One way or another she is losing something.
At the end I also think the show should not have more than 2 seasons, there isn't much to say you can just cut the chase and let the message come in. Otherwise it will be like going back and forth to the same thing all the seasons.
As a show it's worth watch until now.
