The Star reports Parker has been house hunting in New York City solo.
Back in August there were rumors of infidelity. Star reported in August that Parker caught Broderick with a younger woman.
The couple reportedly tried to work things out for the sake of their 4-year-old son James Wilke.
The tabloid quotes and insider: "Sarah Jessica is determined to get her own place and bring down the curtains on her marriage.
"They're essentially living separate lives.
"The truth is, Sarah and Matthew still do love and care about each other, they just aren't in love, and they don't want to waste any more time trying to repair something that's irreparable."
What the El!?! Editorial:
It's sad, they seemed like a couple in love, but everything isn't always as it seems.
But if the marriage is over no need to drag James Wilke through it all.
