Technically I am not still married. I am legally separated. It is a different status at law and in the eyes of society writ large.
I do not hold myself out to the community as a married man; Herself does not hold herself out to the community as a married woman -- indeed, she publicly and openly holds herself out, by her own admission, as a single woman.
We did in fact run into each other this a.m. during the kid exchange and she was dressed to the nines, with more cleavage on display than I'd ever seen. And when I said, "Wow. Must be a hot date today," she blushed redder than red and tossed her hair which, in the body language of Herself, always = Totally Busted.
She will talk about this date with all of her friends -- that is her way. She will talk it up beforehand and dissect it after. She has announced to all the world -- even to me -- her desperate, desperate desire for sex with a new man.
So I have no "wife" in the eyes of the public, and since I have no gods I have no marriage in the eyes of them, either.
The only "I'm still married" argument I could make would be one based purely on will -- I WILL consider myself married until I'm not.
But in every practical sense of the term, except for the rapping of the judge's gavel, I am not married. So I can hardly be "stepping out" on my wife. As there is no woman in the world at this time who claims that title.
