I'd suggest going along regardless of what he says, and YOU deciding if you need it. With all due respect to your OH, is he some kind of recovery expert? My OH had a lot to say about my drinking / recovery. None of it particularly helpful. He'd say 'just cut down' or 'you only drink like me, so you MUST be okay' (LMAO ).
Why my OH just can't 'get' is that there is a lot of difference between abstaining from drinking, and recovery. I chose recovery, and don't regret that for a second. The idea of returning to the tsunami of negativity inside me fills me with horror.
