After splitting with her boyfriend nearly a year ago, Fantasia Barrino is still bitter that ex Antwaun Cook went back to his estranged wife, RadarOnline.com is exclusively reporting.

And not only did Cook go back to Paula , but she helps care for the son he had with Barrino when he has custody, and if it weren’t for 2-year-old Dallas the source says Cook wouldn’t want anything to do with the former American Idol https://radaronline.com/category/tags/american-idol winner.

“Antwaun’s life is all about his boys right now. He loves those kids more than anything, and doesn’t miss the drama with Fantasia,” a source close to the situation told RadarOnline.com.

“If it weren’t for their kid, he’d want nothing to do with her. He’s happy with Paula and what they have going on right now.”

As RadarOnline.com previously reported, pals of Barrino, 29, feared she was suicidal in Jan. following Cook leaving her for his wife, but she quickly tried to squash those reports.

“He and I are not together. I’m not going anywhere so stop trying to make me Dead,” she wrote on her social media.

The source tells RadarOnline.com that Cook and Barrino speak as little as possible.

“Fantasia just hasn’t really moved on , meanwhile Antwaun totally has. He’s back with his family and wife, has a new job and is happy,” the insider revealed.

“But Fantasia’s career isn’t booming and she doesn’t have anything on the table romantically.”

Two weeks ago, Antwaun Cook lived a low-profile life. A father of two sons, he managed a Charlotte, N.C., T-Mobile store and recently joined a local real estate office as an agent.

But one court document and a bitter separation later, he finds himself immersed in headlines as the man who began dating Fantasia Barrino – while he was still married.

The American Idol season 3 champ, 26, initially denied she had broken up Cook’s marriage to his wife Paula but later confirmed she had been in an on-again, off-again relationship with him for 11 months.

Barrino, her manager said, believed Cook when he told her that he and his wife had “separated in the late summer of 2009.” Even back in January, the singer spoke to PEOPLE about her relationship with Cook (whom she said was “separated”) and dismissed claims he was cheating on his wife with her.

A complaint filed by Cook’s wife, however, tells a different story. According to the legal papers, the couple, who married in October 2005 and have two boys together, Christian, 6, and Jackson, 2, only started living separately on June 16, 2010.

Wife’s Allegations

Among some of the wife’s allegations: Cook and Barrino carried on an affair before she split with her husband, even making a sex tape, the two frequented “bars, restaurants, nightclubs and the like” together, and that they had matching tattoos.

An East Carolina University business alum who played football at the school and was a member of the Kappa Alpha Psi fraternity, Cook obtained his real estate license in 2006 so he could “share the knowledge from my own ‘good’ and ‘interesting’ experiences in the homebuying and selling process,” he says on a Web site for Keller Williams Realty, the firm he joined in August.

Describing himself as “extremely motivated” on his LinkedIn profile, Cook has also had an 8-year-long career in the telecommunications industry, including his other current job as a retail sales manager for a local T-Mobile store – where he apparently first met Barrino.

In the complaint, Cook’s wife seeks custody of their two kids, along with child support and alimony.

But there’s a chance even more legal action may take place. Barrino, who was hospitalized Monday for an overdose, could potentially face a lawsuit, because North Carolina is one of seven states that allows a party to sue a “home wrecker.”

So what attracted Barrino to Cook in the first place? She previously told PEOPLE she wasn’t interested in being with a guy who worked in the music industry. “He doesn’t rap or produce,” she said. “He’s from my hometown. He’s just a regular dude.”
