The 51-year-old actor and his actress wife, 45, recently announced they are headed for divorce after 17 years of marriage — and now we know what may have led to their unfortunate split.
"It gets hard — he has a very busy Hollywood career, and she’s been very focused on being a mom," a source revealed to People on Wednesday, May 31.

The couple previously tied the knot in May 2000 and are parents to two kids, daughter Ella Olivia Stiller, 15, and son Quinlin Dempsey Stiller, 11.
"They are a very loving family. [Christine] and Ben respect each other and will do anything to make sure their kids are happy," the insider continued.
Ben and Christine — who have co-starred in five movies together — confirmed their separation to Entertainment Tonight with a joint statement on Friday, May 26.

"With tremendous love and respect for each other, and the 18 years we spent together as a couple, we have made the decision to separate. Our priority will continue to be raising our children as devoted parents and the closest of friends. We kindly ask that the media respect our privacy at this time," the couple said.
In a previous interview with Parade magazine, Ben gushed about meeting his future-wife, Christine, for the first time back in the late 1990s.
"We just started hanging out with each other and it developed into, 'Wow, this feels great. I really like this person. I think I love this person. I really do — I love this person.' It hit me out of the blue," he said.
