Those who have never known the deep intimacy and the intense companionship of mutual love have missed the best thing that life has to give.
Bertrand Russell

Passion is the quickest to develop, and the quickest to fade. Intimacy develops more slowly, and commitment more gradually still.
Robert Sternberg

Intimacy can be about holding someone's hand. It could be about stroking their hair.
Hill Harper

If you age with somebody, you go through so many roles - you're lovers, friends, enemies, colleagues, strangers; you're brother and sister. That's what intimacy is, if you're with your soulmate.
Cate Blanchett
