It would be interesting, perhaps, to know how many people would check the box 'I am an egotistic self-centred git who can't sustain a relationship with or without photography but find it convenient to blame it on photography' -- assuming, of course, they had the cojones to be honest.
Then again, looking at 3 fiancées and 2 wives, the first fiancée, whom I never married, got me into Leicas: she bought one, admittedly on my advice, and I borrowed it; our darkroom was in the basement of her parents' house. I married the other two fiancées: the second was a graduate of St. Martin's and photography is only one of the media in which she works/worked (poetry, welded sheet steel, songwriting, oils, prose...), and the third, since 1981, is Frances Schultz, who is probably a better photographer than I am, and certainly a better printer.
Moral: if photography is important to you, don't try to hide it, and don't choose your partners on the basis of "Lead on, Dick, and I'll follow." And if a happy, stable relationship isn't important to you, why pretend otherwise?
Cheers,
