I completely understand why you feel you need to know if the A is still on. I understand how that affects your decision to stay or go.

Perhaps something to understand here is, you don't trust your W, yet you trust that she is going to give you a straight answer.

Does this make sense, to you?

If you really need to know if she is in an A, either become an extremely good PI, or hire one.

Or separate from her until she finally gives you the answers you are seeking...

But that is entirely up to you...

DO what you need to do, but you appear to be in a really bad spot right now and feel you need to do something... so do... something... that will get you out of that spot of feeling helpless...
