I don't think you will open his eyes.
I had mine in detox at my house, shakes, sweats, everything.
I had him hand his vodka bottles over to me.
I had him cut down.
I had him confess he was out of control, low self esteem, an alocholic, take time off work, binge, beat himself up, then drink again.
Nothing worked.
And you know what?
When we broke up he still couldn't see the drinking was the problem & went into denial saying he was a social drinker only.
Now he's just found another partner who will enable him.
I wish with all my heart I could've made him SEE. We may love them, but we have to let them go.
They don't see & until they seek help for themselves & that may never happen.
