Is she asking you for help in regards to her finances?
You have been at this a lot longer than me, but personally I would let her walk her own path. The moment she "fires" you as a husband should be the moment you stop being her safety net. Unless, of course, it involves the children.
I still get asked for help on various things all the time, but unfortunately I no longer fill that role in her life. IMPO she gave that up when she filed, but each sitch is different so ultimately it will be up to you to decide on if you should or shouldn't.
This is a painful road and there are no right answers. What works for some don't work for others so good luck my friend.
