Old GD, versus new GD. In just the few weeks of knowing your online personality, you have become an amazing person. I have seen a huge change.
I fell like I'm in much the same sitch. I'll be there, but it can only extend so far. My W if unhappy, I was controlling. But she is also really upset with herself and thinks a new life will bring happiness. Everything I see so far says no, and everything I read says it won't.
My only advice is stick with your gut and hold strong to your convictions. You have a plan, follow it through. Keeps your dignity and self respect, no matter what happens.
