I wouldn't have a problem with it, if YOU were initiating (you're not -- she is), you didn't have prior charges of ASSAULT from this woman (you do), and if you weren't responding to her at the drop of a hat (you are -- 15 minutes??? god, you're easy!!).
I hope you are DOCUMENTING all of these encounters. Get some, as they say, "contemporaneous" evidence, meaning TELL A THIRD PARTY each time it happens, so that they can later testify on your behalf, if need be.
And I don't want to hear ANY more nonsense from anyone that your wife still lives in fear of you. That's obviously b.s. now.
