Glad that reading helped, I love the book Language of Letting Go.
I found that I was "victimized" until I said "enough" and stopped putting up with it. I too didn't lay charges for various reasons/excuses when I was stolen from, even after several times. Today I would give one warning only and take it to the max second time in.
When I had enough I said "if you ever do that again I will call the police, have you arrested and tell them everything I know about you and your addiction. It might just save your life."
He never stole from me again.
The stolen cheque (especially from the middle of the cheque book), piggy bank robbing, stolen jewelry and valuables...these are all old stories here, we've all paid the price but we can stop the moment we say "enough".
Hope it gets better for you. Wish I had done what I suggested here a lot sooner than I did. We're ready when we are ready and not a moment before.
Hugs
