The Roseanne-Tom breakup lasted almost a whole week, as Roseanne Arnold announced Thursday that she’s withdrawing a divorce filing against her husband and is planning to reconcile.“I must apologize to my husband, Tom, and to my dear friend Kim Silva for letting outsiders, nasty gossip and lies finally break me down and leave me reeling,” she said in a statement. “Please forgive me to everyone I love. I just lost it completely and found myself camping in the Sequoias. I am off for a much-needed rest to attempt to put my marriage and my head back together.” Arnold didn’t entirely withdraw charges of physical abuse found in the divorce petition filed Monday, but did state, “Tom never hurt my children, and often our fights in the past have led to physical action which we both are learning to control.” Sources discount the notion that the whole incident was a public-relations hoax, but say instead it was a sign of the star’s mercurial nature, which has made dealing with her a roller coaster ride for both ABC and the Carsey-Werner Co., which produces “Roseanne,” her 6-year-old hit series. After news of the couple’s public blow-up surfaced last Friday, Roseanne Arnold canceled a scheduled appearance at UCLA and told associates she was going on vacation (Daily Variety, April 18). The star was said to have taken a similar step last fall, when her sudden retreat to a spa forced a brief production hiatus of her show, on which Tom Arnold is an exec producer. The initial flare-up was widely witnessed, with security guards posted outside the show’s production office and the couple’s home, denying Tom Arnold access. Arnold and his assistant, Kim Silva, were said to have been dismissed at that time, with Roseanne Arnold accusing her husband of an extra-marital relationship. Tuesday, two days after the story broke in Sunday’s weekly Variety, Tom Arnold began conducting interviews, saying that he wanted to reconcile with his wife, denying such a relationship with Silva, as well as the charges of abuse. Arnold issued his own statement Thursday, saying, “This is a great first step toward a healthy and loving resolution of the crisis.” Even at the height of the media frenzy — with TV camera crews staking out the couple’s home and the CBS lot where their shows tape — many observers doubted that the couple would be able to remain apart, citing the volatile nature of their relationship. “Roseanne” has proven remarkably durable with its audience despite its star’s high-profile skirmishes. Her commitment to the show has also remained paramount, despite frequent volleys and public broadsides fired against ABC and Carsey-Werner. Officials at both companies have patiently endured the star’s antics, the latest of which have stemmed from a three-year renewal deal on “Roseanne” that the Arnolds have claimed was cemented without consulting them. Despite their representatives’ insistence that the initial split was in earnest, more cynical industry watchers speculated that the whole brouhaha was calculated to deflect attention from a harsh “60 Minutes” piece last Sunday questioning repressed-memory therapy, in the context of charges of abuse and molestation Roseanne Arnold has levied against her family.
