Thanks again Spitfire and Amy (see previous post regarding
your feedback).
Wanted to add this update:

I got a call early this morning from the fraud department of
a credit card, trying to reach H to verify some "unusual
activity" on one of his credit cards, in LAS VEGAS !
(we live in Colorado). I had a feeling he had gone out of
town with OW for the weekend, so this just verified my
hunch.
I know I shouldn't be surprised or care about anything H does anymore, but it did hurt to know he went there since
since we use to take a lot of trips we really enjoyed, and especially to Vegas, since we went there this past Feb to celebrate our anniversary and Valentine's Day (during what
ended up being a "false" recovery).
It seems that H had a chance to break free of the affair
and give us and our marriage a chance at a fresh start when
OW moved out of his house and they "broke up" about a month
ago, but instead he apparently reacted to yet another of OWs
ultimatums by filing the paperwork, then taking HER on a
trip so they could have a "fresh start". (undoubtedly with
him paying for it all and staying somewhere nice, so as to
"impress").
I've mentioned that he seems to follow a pattern, and this
is another example, as H and OW went to Las Vegas last year
just about this same time, to finally meet "in person" after
they had met online, talked on the phone and TM for awhile.
(OW at the time lived in another state).
As an added irony, H's credit card company called last year,
checking on the same thing, which is how I had found out he
had gone out of town (although at the time I didn't know
about OW and H insisted he had gone alone). Strange, huh ?
