One last comment, when someone starts living a secret life and covering it up with lies, they do strange things. As they go further down this road, the lies compound and the person begins to change. At some point, you don't even recognize them anymore.
Watching someone transform in this way is scary. If I didn't see it for myself, I wouldn't believe it.
You really need to get away from her as she goes down this road. You don't want to be around to watch it. It will tear you up emotionally.
