Just a "for the record" prediction before you post the texts.

She will first attempt to say "you don't know anything," but then -- when you haven't responded to the first couple of texts -- she'll start to spin and position the trip as "just friends." Came to support me during this difficult time, couldn't afford two rooms, etc. Then (and this may even be in texts that haven't been sent yet, and/or vm messages that she will leave you), she will swing wildly between blind rage and then -- when that doesn't work to get a reaction out of you -- a sudden sweet-talking and surge of seeming respect.

2nd choice is she cops to the whole thing, but justifies it with a blanket "I decided our marriage was 'done' a long time ago, so I don't regret this at all," etc., etc.

Just guesses.
