This is pretty much "script." Try to be a good listener -- validate ("That must be hard," and "I'm sorry you feel that way," etc.) -- but don't rescue or blow smoke up her ass.
Treat her like you would a cousin, or a good roommate. Be polite.
Good job on the hugs. It's incredibly hard when we see our wayward/walkaway wives hurting, but it's important to let them FEEL the consequences of their decision-making, and to not rescue them from them.
