EvolvingMe I don't think that helping her by getting a home equity loan would be in your best interest.
My h had to fall on his face and be held accountable for his action with the way out of control spending he did for over a year. He has finally started to catch up on his bills. It took him almost loosing his car and being evicted to snap him back into reality.
IMHO, I would not be supporting 2 households. Remember this is her choice. If she decides to file for D, how would she be financially then? You probably would be giving her less money.
I wished I could give better advice but this is how I had to handle it before my finances before I went broke.
