WAW/Affair Exposed - Advice? #3

[DCBHM]

I re-read "Not 'Just Friends'" from cover to cover last night. I'm apparently in the lowest statistical chance:

Young wife (22)
Young marriage (2 years +/-)
Long-term EA/PA (4-9 mo)
She filed divorce to pursue new R
She refuses to admit the A
She is showing little to no regard for children's welfare
Possibly undiagnosed-BPD (Splitting black/white)

Just going through the motions... but maybe will have a chance to at least get her in therapy.
