The alleged split between what was once one of the most talked about couples in Hollywood, Ben Affleck and Jennifer Garner, has been a long time coming.

According to reports from New York Daily News, the end of their marriage has been years in the making, as one of the family's neighbors gives the details about their rumored divorce.

Although they have been attending awards shows together, and trying to keep a united front for the sake of their children, the source claims that the two have been living together, yet apart for a very long time.

"They had good times when they were living in Brentwood and hanging at Matt [Damon]'s house," says the insider. "Things were definitely a lot more upbeat and optimistic then. Now there's friction and tension between them. They're like two ships passing in the night."

Reports of divorce have been following the couple for almost a year, but according to OK! Magazine, the couple is officially separated and Affleck wants the official statement to be released just a few weeks before their 10^th anniversary, which is approaching on June 29^th.

The insider from New York Daily News gives more insight about what may have caused the split.

"Ben only likes things his way or no way," says the source. "He's as stubborn as a mule, He's not exactly flexible. He is prone to moodiness when he doesn't get his way. Dealing with him is not a walk in the park."

Still, some hope they will work it out for the sake of their three young children.
