Sorry to hear DG; that surely sucks.

You need to talk to a lawyer ASAP. Whether or not you start the ball rolling towards divorce, you need to know where you stand, and what you need to be doing.

In the meantime, start putting things carefully away, leaving them with trusted friends. Need definitive proof, get a camera pointed on your med bottle...

And more than anything:

CYA!

Cover Your Ass!
