The only person he SHOULD stop drinking for is HIMSELF! He had a wake up call and that was his incentive. I do agree though, he’ll relapse when the going gets tough.
But, enough about him. Back to you... Could your addiction to him be boredom? I know you say your LIFE is busy but is it busy with routine stuff – keeping house, kids, job? Like giving up smoking, the best way to get through each craving thought is distraction and a bit of willpower. Is there anything new you want to learn – a hobby/craft/sport or something towards a career?
For a bit of a giggle … When I was having a fixation / fairly obsessive crush / limerance on a guy where I ended up pissing myself off with my all consuming thoughts about him (and he was a bit of a weirdo and I don’t really know what I liked about him), I ended up telling myself I could think about him for an hour a day at 5pm (when I was driving home from work, lol). The rest of the time, as soon as he popped into my head (often) I literally told the thought to fuck off, wanker and made a conscious effort to distract myself / think about something else. As you can imagine, I was saying fuck off, wanker quite a lot at first
and I started to force myself to find the most mundane things utterly fascinating (washing the pots, really concentrating on that telly programme, the work I was actually supposed to be doing, re-reading that paragraph for the 10th time in the book I was reading, and so on). Then when “thinking” time started, I kept dragging my thoughts BACK to him (you will bloody well think about him until you’re sick of it, sort of thing). Turns out I got quite annoyed with having to do that and it got a bit boring after a while, so I cut the “thinking” time down to 30 minutes, then 15, then 10 then just a fleeting thought passing through my brain. It took a few months and a lot of perseverance, but it worked.
The mind is a funny old thing.
