If you have not read Michele's article on the Symptoms of the WAW, you could find out a lot. You can find it here on DB's home page.

If your W had two EA's in a three-month span, she really has something going on that a professional needs to help her with....and I hope her IC is very good. I don't tell you to move on to discourage you, but this might run into a very long and serious journey. DBing may not be enough to turn her around. I hope she gets the help she truly needs.

Does she have other addictions?

It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
