Why does your narc husband call the police on you?

We do not have the details of exactly what is going on in your marriage, but I might speculate that perhaps your narc husband calls the police on you because you are spending all the family money on recreational drugs, and he would like to be able to pay the rent. There are many other possible explanations. Maybe he is hoping to get a divorce so he can marry the cute waitress down the street. You should probably talk to him about this, rather than talking to us.
