Imho, you should never be put in such a situation, let alone get an attitude when you need to leave after hours of torture.

Think of it this way, Bif: you are the only one at the gathering not destroying their liver!

Kudos to you!!!

Which is exactly what you need to do in a situation such as this.

I have a daughter of who is recovering addict. She can't be around other addicts because she knows what will happen. She will be clean almost 5 yrs now.

That since she and daughters arranged and intervention she would be more aware of the problems involved in hanging around people drinking. The next time there is an event that requires you and your wife to attend that involves alcohol you might want to set up some time frames between you as to how long you are willing to deal with it...

Personally I have 41 years sober and still will not hang around long at parties and other events that involve alcohol....Cannot stand being around drunk people.

friends how difficult it can be to be around drinkers when one no longer drinks. One would think that your wife would understand this, especially if she arranged the intervention.

You should be proud of yourself for staying strong.

Those situations should be negotiated ahead of time, perhaps, so you both have an agreed upon boundary of when to leave. Family dynamics and booze, ugh.

you hang out by yourself at the top of the slope, for hours.

and next time either take two cars (if you can) or call a cab or Uber or whatever and leave when you start feeling uncomfortable. When you are sober, it's not fun when everyone else is starting to show signs of intoxication. They get loud, sloppy and well, you know...

You should have seaparate ways of leaving.
A glass of seltzer with lemon or grape juice that never goes below full can help with awkwardness in some situstions. But I suspect you are already all over that.

Yesterday I went to a baby shower for my nephew & wife- held at a microbrewery. Of course they had plenty of non-alcoholic drink for the kids and those who don't drink beer. Conveniently, I had another obligation 2 hours later, so we didn't stay very long.

It sounds to me like your wife is not very supportive of your sobriety, which is unfortunate. Taking separate cars, or leaving early via Uber are ideas you might want to consider.
