The estranged wife of a prominent New York City investment banker who accused her hubby of partying with his Jefferies & Co. colleagues and clients has reached a tentative deal to settle their fantastically ugly divorce — and issued a public apology to her husband's employer late Monday.  "A substantial portion of what has been written in the press and other media over the past few weeks is inaccurate, untrue or hyperbolic, and I apologize to those who have been affected thereby — including those at Jefferies and those associated with Jefferies," Christina Di Mauro Kelly said in a statement first issued early this Monday through Bloomberg News.  The statement does not say that she said anything in her filings against Sage Kelly that was necessarily untrue. "The presentation of the facts in divorce proceedings is a function of subjective viewpoints," the statement said.  In the statement, she also called her husband — who she accused of going on wild benders with prostitutes — a man of "high integrity" and a "great father."  The wife — who now once again goes by the last name Di Mauro — declined to comment on the statement, but told the Daily News she was "thrilled" that her divorce and custody fight are over.  "It's been quite an emotional past three months for me," she said Tuesday morning. "It was never about the money — I just wanted joint custody of those girls," she said of her two daughters with Kelly.  "They need their mommy and I need them."  "This is how it should have ended," she said, adding that she was "looking forward to moving on and a new life, a new chapter in my life," and putting "this messy, messy divorce behind me."  Di Mauro's lawyer, William Beslow, declined comment.  The couple's divorce fight exploded into the public last month, when Di Mauro filed a $7 million lawsuit against Kelly, accusing him of making false statements about her drug and alcohol use in their divorce case in order to keep her away from their two kids.  The suit painted him as an incontinent, drug-abusing wife-swapper who would get so blasted that he'd relieve himself wherever he was in their Fifth Ave. apartment or Sag Harbor home.  Jefferies & Co. — which was deeply embarrassed by the suit, which had named names — announced last week that Kelly had taken a leave of absence from his job to focus on his family.  Sage Kelly "is embroiled in a deeply personal and painful situation and, as such, we have decided to accept his decision to take time off to focus on doing what is in the best interest of his children," Jefferies & Co. CEO Richard Handler said in a memo to staff, which was obtained by Bloomberg News.  "We cannot express how deeply we regret the agony and distraction that this has caused all of us, not to mention our clients, each of whom has categorically denied the allegations.  "We are not happy to be in this unfair position," Handler wrote.  Kelly, who makes $7 million a year, denied his wife's allegations and pooh-poohed her claims that he'd had accidents all over the house.  "I have never defecated or urinated in bed, on the floor or a wall," he said in court papers.
A deal was reached between Sage Kelly and his estranged wife, Christina Di Mauro Kelly, though details were not revealed.
