I would not meet with the XOW under any circumstances. Don't give her the power.
If I were H, I'd go to the Apple store and work with them to disconnect the phone. Is the phone under H's plan? If yes, then I'd ask the store to disable it. If it is under XOW's name and credit card, then it'd be best to cut your losses and move on from that situation.
You and H need to extract yourselves from OW in any way possible without SEEING her at all. Scratch option #2.
Doesn't the OXW have an email that H can send the NC to as most iPhones tend to have the @gmail.com account.
Good luck!
Actually, as I re-think this, I agree with this from Wonka ^^^.
Nothing good can come out of such a meeting. I originally thought "he/they will never go for that option anyway," and kinda liked the firmness and snarkiness of the way you phrased it, but upon further reflection you shouldn't even offer that option.
