I want to leave my husband, but everytime I try my plan gets foiled. Someone give me some tips on how to leave

I have been with this man for 14 years and I want to leave. I have tried everything. I even went stay at a shelter to get away and the shelter put me out for no reason. I was devistated, all I wanted to do was leave. Can someone tell me some good ways to get out. I dont care if I have to leave everything. I just want to leave and be safe. He has terrorized me and even flattened my tires. He was stalking me at my job. The police here are a joke and have laughed in my face. Can someone give me some solid information on how to get away or some resources?
