Rounding out a summer of shocking splits, Jon Hamm and his girlfriend of 18 years, Jennifer Westfeldt, announced this weekend that they were separating. According to insiders, there was trouble in paradise for several months now and RadarOnline.com has exclusively learned about the final straw that tore the couple apart. Click through these 9 photos to learn why – after nearly two decades together – they decided to call it quits.
"The real reason that he and Jennifer split was because she wanted him to commit and he was just not ready," a source close to the 44-year-old actor tells Radar.
Photographed together here in 2014, the couple looked healthy and very much in love. But was it all for the cameras?
This photo of the Hamm and Westfeldt shows why it isn't just his big paycheck that made him one of Hollywood's most desirable men in recent years.
It's no wonder why Westfeldt ALWAYS looked so happy!
But, apparently, it takes more than just good looks to keep a woman happy because the source tells Radar, "Jennifer told Jon that she never imagined that after almost two decades together, he would still have not asked her to marry him."
In the past year, Hamm has been struggling with alcoholism and, as Radar reported, spent 30 days in a rehabilitation center this past Spring.
According to the insider, after Hamm was released from rehab at the end of March, "All he did was constantly pick fights with Jennifer. They would go to war over everything."
"Neither one of them could trust the other one towards the end," says the source.
"It just got to the point where they both realized that they were better off without each other."
