RTL - I hate to play devils advocate, but as wishful thinking it is to be thinking that OM is dumping W and is the cause for her migraine, you also cant get your expectations up to high. Just be prepared for her to possibly cross back over to the dark side. If she does, just dont let it get you down. There will be ups and downs on this journey of waiting for your W to return from being totally taken over by the dark side.
