Just stand back. They've both got enough rope right now to hang themselves 12 times. It will happen. That relationship needs to come to its natural end. I found that out with FW.
Once we step back and allow things to play out with them the way they need to for the relationship to really be over then the healing can really begin. It can't until then.
You're doing much better.
