Hi Reachingout
Welcome to SR.
First things first. You recognise you have a problem and you want to quit. That's a fantastic start. You will come to realise that you can't expect your wife to "help" you quit. This is something you need to want and do for yourself. She needs to take care of herself while oyu get healthy.
Secondly, you might find it helpful to use your signature name and Reach Out for help. Quitting and staying quit can be really tough on oyur own, especially if you're struggling to fill your day with activities. AA is a brilliant starting point. Some people have diferent perceptions of AA, but it's almost certainly not what you may think. You will meet folks from all walks of life there and they will be able to share their experience with you.
Give it a try and please come back here to let us know how you get on.
My thoughts are with you.
Rich
