My best advice is allow her to work to earn your trust again.
I think I let my WAW back into my life too easily. I felt like I had won the lottery. As a result, I don't think she respected me as much as she should have.
What are your boundaries?
What are your deal breakers?
What changes do you expect from you and your W?
If you don't identify these things ^^^, you are setting yourself up for another bomb.
I wouldnt worry about when to move back in at this stage. Do it too soon, and I feel very confident you will be moving back out pretty quickly.
Just take things very slow. See if you can find a Solution Based Therapist and have your wife join you. You need to get to the root of why this all happened before you can jump back in with her.
