I wouldn't have a depressed partner--one of us with those tendencies is enough. I mentioned that to a relative, who seemed insulted.
Chronic depression is one of the most life-sapping conditions there is. The same relative later remarked to me that they think they had been robbed of a good part of their life by the "black dog." And that's with medication.
So unless you happen to meet a sex-positive African-American minimalist who can take or leave religion and children, enjoys dogs, and likes the idea of being the companion of a morose, moody, glass empty and dry as the Mojave kinda guy, you should probably cultivate the joys of solitude. Or any joy at all.
