The very civilised development in the Ben Affleck and Jennifer Garner split.

They are getting divorced, but they’ll still be roomies.

When you decide to separate from your long-term partner, a little space is in order.

That’s why Ben Affleck and Jennifer Garner, whose divorce announcement was made yesterday, are going to live in the family home together.

Wait, what?

Separate lives. Same house. Ben Affleck and Jennifer Garner are splitting up, but staying in the same house.

Well, when your house is a palatial 9,000-square-foot palace-type abode, you can avoid one another with ease by simply choosing a wing.

I’m envisioning Affleck in a “man-cave” style space with his buddies playing poker, Budweiser in hand. Garner, she’ll probably refurb her part of the house to signify a new beginning. She may also get a haircut.

The Bennifer II years… Post continues after gallery.

US Weekly reports that while Affleck will live on the property, he won’t be in the main house.

Now, if my partner and I were to break up and continue cohabiting, we’d probably run into each other from time to time (in the bathroom, the kitchen, the bedroom and the couch, mostly). But it would save us from having to split our cat evenly in two.

Bennifer II shouldn’t have much trouble avoiding each other, unless their kids undertake a Parent Trap-style reunion.

Their house in Pacific Palisades property in LA cost $17.5 million when they bought it in 2009. I wonder how many guest bedrooms that buys you? I’m going to say 12. Twelve bedrooms.

Here is an aerial view of the small city family home.

The pair have said that they are “going forward with love and friendship for one another” and a “commitment to co-parenting” their three children, Violet, 9, Seraphina, 6, and Samuel, 3.

Good luck to them.
