Teke,
Okay, you're on to him now. The object is not really to let him know that you are on to him. Maintain a low profile, see that lawyer and maybe, while your AH is out of the house, have a handyman, or someone come check out that house alongside you. Take pictures if you can.
Take a deep breath, get to a meeting if you can, Serenity Prayer, like Cats suggested, and put the focus back on YOU.
Hugs, and stay safe.
Excuse my judgementalness, but he sounds like a nut.
Hugs to you,
