The McCartney's way....

"I always think of Linda still as my girlfriend. That's how we started out in the '60s, just as friends. Whenever I was working late somewhere, I just never fancied it. I thought: Well, I could stay overnight in this posh hotel, or I could go home to Linda. And it was always the brighter of the two options: Yeah, go home to Linda. It was just I liked being with her, quite frankly."

One thing leads to the other...
