I think your wife is simply laying low, and being nice to you, until:
- this nice vacation you're paying for; and
- she sees what your legal stance is going to be.
Someone doesn't go from 1400 text messages in 20 days, to "only one since 5/6, just to break it off with him." (and again, you used the passive word "hopefully" there).
Once the vacation is over, and she sees that you're not going to give in to her legally (unless of course, you DO), I think you're going to see the re-conflagration of her affair.
