It's hard to stay out of someone's relationship (or non relationship) when one of the parties concerned is someone you're invested in. I imagine that it's even worse if you're invested in both parties in the relationship. Your concern needs to be on your relationship with W. It's up to him to communicate with you how things are with him and when he's ready to resume communication with P and what that communication will look like. It's your responsibility to continue being open about how you feel with him and what you need from him. It isn't your responsibility to act as messenger between the two of them.
Everything will be ok in the end. If it's not ok it's not the end.
