solicitude

I agree with this, don't let him back into your home, not even to stay one night.
And yes, you are lucky it hasn't been much more, already. He could have access to bank accounts, and other things, too. If you keep letting him stay there it will ONLY get worse- if you don't stop it he will see it as "she will still let me around, won't call the cops, she doesn't care because she has plenty of money, etc". I kept believing the words of my ex addict and he stole 700+ from my parents that they were saving up for my 80 year old grandparents, probably another 500 or so from my wallet over time, he stole a lot of my jewelry which wasn't worth much money but was all I had left of my now dead grandmother and cousin, he stole change from a bucket I was saving for my son's bank account, and lots of other things, even food from my freezer for some reason.
