Chris Martin, Gwyneth Paltrow Touching

Chris Martin and Gwyneth Paltrow may have figured out the whole divorcing thing ... figured it out better than most, because they still genuinely seem to have affection -- if not love -- for each other.

Chris, Gwyneth and their 2 kids went to Katsuya in Brentwood for dinner Tuesday night. They left separately ... Gwyneth and the kids in an SUV, leaving Chris behind.

But the SUV drives a block from the restaurant and then stops.  Chris sprints over to his family, and then you see a touch that tells a real story about the relationship that remains between the two.

For all of the warring divorce couples ... watch and learn.
