With her chaotic past behind her and a newly empty nest, she focuses on her marriage to her husband, Adam (William Fichtner), and on what she wants to be now that she has finally grown up.
[4] Now more than ever, Bonnie depends on the support of her friends, including the wise Marjorie (Mimi Kennedy), the wealthy and sometimes misguided Jill (Jaime Pressly), the overly emotional Wendy (Beth Hall) and her loudmouthed but sweet former foster sister, Tammy (Kristen Johnston).
When Christy leaves for the East Coast to attend law school, the women plan a surprise slumber party in honor of Tammy's birthday that becomes somewhat tense when Marjorie reveals a health problem.
Meanwhile, Jill accidentally donates a huge sum to charity and feels some Tammy-prompted guilt over clawing back much of it, before eventually doing the right thing.
Meanwhile, Tammy lends a hand to the recently-fired Chef Rudy as he starts a new food truck business, and sparks ignite anew between them.
Adam's excitement at going skiing for the first time since the accident that paralyzed him provokes Bonnie's deep fear of losing those close to her, but a dream visit from Alvin reassures her.
Meanwhile, Jill copes with Andy's request for a break in their relationship by helping Tammy with a teen girls' mentoring program.
However, the girls get hooked onto Jill dramatizing everything, and she ends up using them as a makeshift service to get back at Andy on social media.
Jill suspects Andy's hesitance to end his "break" from her is because he's started a relationship with his new female cop partner, so she enlists Bonnie (and later Tammy and Wendy) to conduct a surveillance operation.
Jill looks forward to an appointment with her elderly father figure of a dentist but is devastated to find out he's only got a few months left until he retires.
Adam and Bonnie are ready for their first romantic Valentine's Day together since they got married, but the rest of the group is either out of the romance scene (Jill and Tammy) or getting crushed by it (Marjorie and Wendy).
Marjorie is left downtrodden after Gary breaks up with her by text and she later falls and fractures her wrist, while everyone is intrigued by Wendy's hospital romance until they find out her "boyfriend" is a cardiologist who's married and cheating with her.
Bonnie is shocked and appalled when Adam drives her to see a huge billboard for a local strip club that features an R-rated, 20-year old picture of Christy.
When the club owner (Bob Odenkirk) refuses to remove it, Bonnie sets out to take action, while Marjorie worries that she'll end up in trouble.
When Tammy can't handle the lies anymore, she tells their first client the truth and he fires them, leading to a major argument between the women and a fracture in the group.
Elsewhere, Jill goes through the ups and downs of cutting sugar out of her diet, finally deciding that the "no sugar=smaller breasts" equation doesn't work for her.
The latest women's AA meeting sees the arrival of Shannon, who is not impressed with the stories she hears about how well everyone's life is going and walks out into the rain.
