Jon Hamm, a man who is mad, and girlfriend Jennifer Westfeldt, a woman of indeterminate anger, have broken up, the couple announced on Monday.

“With great sadness, we have decided to separate, after 18 years of love and shared history,” said Hamm and Westfeldt in a joint statement to Page Six. “We will continue to be supportive of each other in every way possible moving forward.”

Rumors of the break-up have circulated since July, when an anonymous source said to be close the couple told Star their relationship had “just ran its course”:

But it wasn’t the 44-year-old star’s addiction that brought on the breakup— it was Jon’s reluctance to start a family with the 45-year-old actress. “I don’t have a driving force to have a baby,” the actor has previously said. “That said, I’m in a committed relationship, and if it ever came up, I’m not ruling it out.” However, sources say he did just that. “Jennifer realized that she and Jon don’t want the same things,” says the pal. “So they agreed that it was time to take a step back.”

In March, Hamm spent 30 days in rehab for alcohol abuse.



“With the support of his longtime partner Jennifer Westfeldt, Jon Hamm recently completed treatment for his struggle with alcohol addiction,” said a representative at the time.
