Not sure you even need to (or should) reach out at this point. Why not let her make the overture? Just pack up her stuff without word and leave it in the garage for when she asks for it. No need to mention the mortgage or property. That will play out during the negotiations and maybe with lawyers.

Comes across a little like you want to make contact.
