Husband is a addict help

My husband is a gambling addict. He has been lying and stealing for a long long time. He’s tried to get help and sometimes it gets better and sometimes it gets worse. We’ve been together for a long time and I just don’t know what to do. I don’t know how I can ever trust him again.
Please please pray for us. My heart is shattered. I literally don’t know what to do every day. I am barely hanging on and don’t know how I will ever get through this. Do I spend the rest of my life never trusting him and always worrying? Or do I go out on my own and break up my family? Both are bad choices. Please please pray for me. I would appreciate it so much. I need help.
