Exactly this.
My DH (2nd time around) is all about his experience with me as his best friend, lover, confidant, and then wife!
To give you an idea, he does ALL the DIY. He's very talented, and it's part of how he unwinds. It's a strength.
I LOVE to cook. It's how I unwind.
Neither of these things are to do with our gender or 'perceived' roles. We just enjoy these aspects.
He also loves yoga, adrenaline fueled experiences, globe trotting whenever he can, theatre, is very spiritual, and he'll talk to anyone and everyone.
I, on the other hand, am not a fan of people in general, cannot abide yoga (no issues with anyone that enjoys it), I am a runner, and do weights. My idea of a good 'show' is a horror movie like Paranormal Activity, I look to science for my answers, and I do not enjoy bungee jumping.
We are both so different, but what bonds us is how we feel about one another. He's not my 'son' - we have far too much sex, are equals, and respect one another as such for that to ever be something I'd feel is even remotely part of our equation.
I think that's the key. Our time outside of the things we HAVE to do is geared towards being with one another. No one goes off to the pub while the other 'stays at home'.
