Not singing victory yet, but if she comes back, AND you take her back, have you read passionate marriage by Schnarch? It's a very tough read, but has some great advice about building a M where BOTH partners can handle dealing with stress on their own, rather than mistakenly over relying on each other.
She ran away from her first M, then you, now she may run from OM, and maybe back to you. Nonetheless she is still running. PM has some great advice on learning how to "self soothe" and how to set the conditions to help your spouse teach themselves.
If things go well fri morning maybe you can pick up a copy afterwards?
