It's made me totally indifferent to non-WG's.
Was married for 25+ years to the only girl in the world that I'll ever 'love', certainly don't want a 'relationship' with another 'girlfriend', certainly not in my age group i.e. late 50's-early 60's widowed/divorced/whatever, don't want 'companionship', got all the 'friends' I want or need. For example, one woman I work with, single mother, just turned 50, two teenage kids still at school, car always breaking down, blah-blah-drama-drama. No thanks.
I flirt with the women I work with if they want to flirt, but I make it absolutely clear that I'm not interested in anything more than flirting.
I prefer WG's, simple as that. For the most part (emphasis on that bit) they're prettier, sexier, cleaner, fresher and bendier than a 'girlfriend/wife/significant-other', all of the 'good', none of the 'bad'.
