Jealousy & Sexless Nights! Inside Matt Damon & Luciana Barroso’s Marriage Troubles—Why It’s Ben Affleck’s Fault!

But that involved excluding Matt’s wife, Luciana Barroso, not only from their constant hangouts, but also staying tight-lipped about anything they talked about behind closed doors.

“Ben, of course, was confiding in Matt about all his relationship problems, but when Luciana would ask Matt what was going on, he’d refuse to talk about it, out of loyalty to his friend,” a family insider reveals to Star.

“That really ticked Luciana off, and she accused him of keeping secrets from her. Things started to spiral from there,” adds the tipster.

Then, when Matt offered their guesthouse as a man cave for Ben, Luciana flew off the handle—their fights exposing Luciana’s severe jealousy issues.

To avoid the fighting, Matt would slip out the back door every day to go spend time with Ben instead of his family. What’s worse, the pair started going on their boozy binges together in the evenings, leaving Luciana to worry about the duo being hungry for attention from the ladies.

“Ben acts like a frat boy around Matt, which she finds obnoxious. And she knows his history as a ladies’ man. She was worried his bad influence will rub off on Matt,” a source tells Star.

Parenting four daughters leaves Luciana and Matt with little time for one another. “And now, with all their fighting, there have been more sexless nights than ever,” a source says.

There’s so much for to this story—more shocking details about their blowout fights, why Luciana won’t let Matt go anywhere alone, if there’s a prenuptial agreement and what’s at stake if this will drive them to split.
