I can't put this on my Facebook page because I refuse to give in to the temptation to use it for personal statements no matter how disguised as insight into a writer's mind.
But I don't have that issue here so this is what I'd like to post:

-- The most boring character an author can put in a book is an ex-wife who hasn't moved on. Whether she was the one who was left or she was the one who did the leaving, if she can't get over it, if she still wants that man, that life back, she's a boring character. No way to make her interesting. Now, an ex-wife who is the villain in a book, now that's good because villains are always interesting.--

That is so tempting...but even veiled as writing commentary, it's still too obvious and I won't give them the satisfaction of thinking they are bugging us. What they want is a reaction and so far, for eight months, non-confrontation and non-response has stymied them and I'd like that continue. Never, ever give the narcissists what they want.
What has prompted this is learning that last month, Dwayne's ex-wife phoned his sister out of the blue, after years without contact, to "fill her in" on everything that has been going on (!?). She opened the conversation by asking so many "Have you spoken to your parents?" and "Have they said anything about what's going on?" type of questions that the sister wondered if she was being taped. When Dwayne's sister finally asked, "Why are you calling me?", the ex replied that she wanted advice: "What do I do about Dwayne?"

Aaaaargh.
If this was a soap opera, I'd be calling her and reminding her that he's not her husband, that the kids are grown up and if she'd been a good mother, they would sort out their own problems without her interference, and he's bloody well not the problem, she is and because of that, her daughter is, so it's more than time to let go and get on with your own damn life since you left this one for another man ten years ago.
But this is real life so my pen is mightier than a phone call (and despite what the daughter thinks, mightier than Facebook too).
