Co-Parenting After the Split: How Sara Foster and Tommy Haas Made It Work

Most relationships that end come with a clean break—separate homes, separate lives, and an awkward dance around shared custody schedules. But Sara Foster and Tommy Haas wrote a different playbook.

Nearly two years after their split in August 2024, the pair still shares a roof. Not out of stubbornness or unresolved feelings, but out of pragmatism and something that might actually be harder to pull off: intentional grace. During her appearance on Kristin Cavallari’s Let’s Be Honest podcast on Tuesday, June 30, Foster, 45, opened up about the unconventional arrangement that keeps their family—including daughters Valentina, 15, and Josephine, 10—grounded.

The setup works because Tommy Haas, 48, is rarely there. The retired tennis player lives as a Florida resident but spends much of his time on the road, away from Los Angeles, where his comfort level has always been low. When he’s in town, they share meals with their kids. When he’s not, the household goes on. There’s no drama in the distance—just the simple reality that Haas’s lifestyle and Foster’s anchor point in LA don’t require them to fight for space.

What makes this refreshingly different isn’t the living arrangement itself, but Foster’s honesty about why they actually split. It wasn’t a dramatic rupture. There was no infidelity scandal or public meltdown. Instead, it was something quieter and harder to articulate: a slow drift. They grew differently. At some point, Foster noticed something shift in how Haas looked at her—a loss of respect that, once visible, became impossible to ignore.“There’s something to be said about slowly transitioning,”she reflected.“Nothing crazy happened. I think you, kind of, grow differently.”

What Foster regrets most isn’t the breakup—it’s how it became public before they’d had the chance to sit down with their daughters and frame it on their own terms. But she’s also clear-eyed about the silver lining: they’ve found a rhythm that works, one that doesn’t require their kids to choose sides or model a version of love that looks broken. Foster praised Haas’s integrity, describing him as someone who doesn’t climb, doesn’t scheme, and isn’t swayed by status. Those qualities—the character that made them partners in the first place—are what make co-parenting possible now that they’re not.

It’s a quiet kind of wisdom: some relationships don’t need to explode. Sometimes they just need space to breathe, and sometimes the people involved are decent enough to give it to each other. That’s not a fairy tale. But it might be something better—a real, messy, human solution to an impossible situation.
