A Mother's Fury

Robbie and Jessica have been engaged for seven years, but he says the wedding is on hold indefinitely — unless she can curb her anger and drinking. Robbie says that Jessica becomes verbally abusive when she drinks and constantly puts him down in front of their three children. Robbie also claims that Jessica has hit him multiple times, including smacking him across the face with an umbrella.

Jessica admits that she has a couple of beers at night to “tune everything out" and says that she occasionally drinks more than she should. She also confesses that she has a "major issue" with anger. Jessica confides that she has lashed out verbally at Robbie and her two older children, calling them names like "idiot," "jerk" and "bitch." "There's only so much that I can take, and then I blow up," she says.

Jessica explains that she feels their blended family is divided — and says she's caught in the middle of the chaos. She claims that Robbie only accepts the 6-year-old son they share — and not her two teenage children. “I feel like Robbie picks on the kids, and I feel like I always have to defend them,” she insists.

What did Jessica's teen daughter catch on video? And, Jessica reacts: "I feel like a horrible mother."

Dr. Phil has some harsh words for Jessica. And, has Robbie started drinking as well?

Jessica’s mother, Sybille, claims that Jessica and Robbie have always had a tumultuous relationship and says she thinks they have no business getting married — or being together at all. "Jessica and Robbie both need help," she insists. Sybille says that she worries about her grandchildren living in a house with "two drunks." "Who's going to stand up and speak for them?" she asks.

Jessica and Sybille face off, and Dr. Phil steps in: "I have no doubt that there is a legacy of chaos here."

Hear from Jessica's older children: "I would like my mom to get better ... and I don't want to live with Robbie."

"You guys have no relationship skills whatsoever," Dr. Phil tells Jessica and Robbie. "You are damaged people, and as a result, you contaminate this relationship, and you contaminate the children in the crossfire," he insists. Dr. Phil explains that children in blended families have special needs — and says that Jessica and Robbie aren't fulfilling them. "You are doing so much wrong that it has to improve," he says.

Dr. Phil tells Jessica that she needs to get help with her rage and drinking. He offers to send her to Hannah's House, a program designed specifically for women dealing with addiction and co-occurring psychological issues. Jessica agrees to take the help.

"While she's gone, you need some help with a parenting plan," Dr. Phil says to Robbie. "I will get that help for you, so she doesn't come home to the same broken situation that she left." Robbie accepts the help.

'Til Change Do Us Part?

Jessica says she lost 100 pounds in an attempt to get healthier after suffering a miscarriage, but she claims that her husband, Brendan, doesn’t support her transformation. “Brendan would never say anything positive about the weight loss," Jessica recalls. "Brendan would say, 'You know, no one else is going to love you like this.'"

Jessica claims that Brendan has always been controlling — and says his behavior worsened as she lost weight. She says that Brendan would check her cell phone and even follow her to the gym in an attempt to monitor attention she received from other men. Jessica also claims that Brendan has made violent threats. "[He] told me that if I ever left him he would slit my throat in front of the mirror so I could watch myself bleed out," she says.

Brendan admits to making the threat, but insists that he would never actually harm Jessica. "The more she started changing, I felt like I was getting left in the dust; and it upset me, and it pissed me off," he confides. Brendan confesses that he worries about other men being attracted to Jessica — but has she given him cause for concern?

Hear what happened during the Jessica and Brendan's separation. "I became the ultimate monster."

Jessica's sister, Heather, weighs in: "Brendan has reasons to be jealous and worried."

Dr. Phil asks Jessica if she wants to stay married to Brendan, and she replies that she's not sure. "I know it sounds bad," she admits. "But to have such a life-changing event of losing all this weight, and the whole time having to separate yourself from your husband because he doesn't support you ... Can you imagine living so alone for a year?"

"I felt the same way. You were moving on without me," Brendan responds. "We had goals when we got married, and you basically said, 'Eh, to hell with them. I'll go do this now, by myself.'"

Dr. Phil tells Jessica and Brendan that they have both made decisions that have put their relationship at risk. "It is clear to me that we have two people here in a marriage who are not really skilled to be in a relationship," he says. But, he adds: "At this point, you guys don't have the right to quit this marriage."

"Relationships are negotiations, and the negotiations never stop," Dr. Phil explains. "People change, people evolve and so the negotiation never stops." He tells Jessica and Brendan that they need to take some time to consciously and proactively work on their relationship. Dr. Phil offers to provide Jessica and Brendan with marriage counseling, and they accept.
