Actor Ben Affleck and Jennifer Garner reportedly separated six months ago and now want a "quick and easy" end to their marriage.

The couple, who have children Violet, nine, Seraphina, six, and Samuel, three, together, announced on Tuesday that they are to divorce after 10 years of marriage.

"This isn't going to end up in a dramatic court case, they are trying to resolve it as quickly and easily as possible. Ben and Jennifer have been separated for more than six months. They have been seeing counselors for years. The situation is that people change and they grow apart," a source told pagesix.com.

Though Affleck has been staying in hotels in recent months, he is planning to live on the property of their Brentwood marital home to stay close to the children, but he will not share the main house with the 43-year-old actress.

The source added: "They plan to share custody and co-parent their kids."
