How do yall feel about the whole 'my gf/bf is my best friend except we bang' thing? My relationship has that kind of dynamic going on. But I know a lot of others who want a little more mystery to their partner, rather than the complete honesty and open-ness of being so close. Which I get, you hear a lot of shit you never want to hear a man or woman say when they're comfortable around you. Farting becomes less adorably embarrassing, and more hilarious.
But I feel like that kind of thing, a sense of mystery, isn't gonna stand the test of time. It's essentially a partnership between people who manage to stay loyal by constantly playing each other and acting like they're still strangers years later.
