OK, so we all know the basics which make for a good relationship - communication, respect, love, honesty etc. But I'm hoping we can all share one SPECIFIC thing you do which makes your relationship good.
For me, I'd have to say that learning to not sweat the small stuff is so helpful for keeping a calm environment. And I know that DH does it back in return for things I might say. It's so easy to jump on everything which rubs us up the wrong way, but I prefer to really pick my battles. To leave my negative reactions for things which are very important.
Not sweating the small stuff means that we never have 'stupid' fights. On the rare occasion we do disagree, it's going to be over something which is significant and truly does need to be addressed.
What do you do to make your relationship a good one?
