I find it terrible that one spouse would divorce the other over not going back to work. But no matter, because your sister's ex is probably leaving her because she's crazy, not because she hasn't found a job. Your sister is definitely in pain and not thinking straight right now, if ever. So try not to let the insults get to you. State composedly that if you testify, you will advocate for shared custody. Let her mull on that for a while.
NP here. But did the STBX husband fully support having a third child and your sister staying home, and then somehow change his mind? Or is this one of the commonly seen DCUM situations where the wife pushed the husband into having another baby and the husband has been asking her for years to return to work and reduce the stress of having only one wage earner? The latter seems quite common, if you believe the posters here. Those are two entirely different scenarios.
OP, I would be completely honest with your sister. You really owe that to her children and to her STBX.
