Sending you a hug.
You're going to hear a bunch of "reasons" this was not his fault...he only had a few, the police were pulling everyone over, blablabla. I was on a jury once where a habitual DUI guy had an expert witness claim he couldn't have been legally drunk because yes, he'd had 12 shots in 90 minutes but he couldn't possibly have metabolized it that fast.
Most later stage alcoholics hide alcohol and sneak drinks, so he may have been drinking while he was with you.
This is him.
Is this acceptable to you to live this way?
