She says that work is the only thing keeping her sane

That I would believe. Seems she's made a mess of her personal life and she's struggling with that, which is good. So her work life is the only thing not in turmoil and she's seeking refuge in that.
Try to stop thinking about her and especially stop thinking about the OM. I know it's really hard to do. Focus on your kids. Focus on your own self and well-being. Keep pulling away from her. Reread Sandi's rules. Rewrite them in the first person and internalize them. You'd be amazed at how well they can work if you have the self discipline and self control to follow them to a T.
It's like trying to feed a squirrel. If you chase after it you'll never catch it. If you sit patiently and very still it will approach. When it takes the food from your hand you still have to remain motionless or it'll run away and may never come back again. Only after many times may the squirrel stay when you move.
