For anyone who may be interested. Things have calmed down...He has been having a JD and coke every other night (to my knowledge) and I haven't shown any reaction.
I just want peace. So I'm getting on with my life and he is getting on with his. He still denies a problem the last time we spoke and although I don't buy it i have to accept whatever is going on. I have lots of support should i need it. The initial shock has subsided and I have stopped questioning him. He seems more considerate towards me now. Perhaps out of gratitude for me leaving him alone. I'm still uneasy about it all but have my outbursts at him under control.😀
