Sometimes its best to come clean. I did with my mum, and she helps abit. But thats up to you. Maybe he could support you better.
Plus its great what you are doing admitting you have a problem. It gets a lot easier, and if you lapse just get back on track, dont beat yourself up. Take up some new hobbies to keep you occupied. You basically need to change your whole routine around with positive things and hobbies.
