A woman meets a man with issues around alcohol. What is a wise approach?

I received an email from a person who has met a man with unresolved alcohol issues.  She asked me what approach to take towards this person and his situation. This is a common situation.

Here is my response:

Dear …

Thanks for message.
Addiction to alcohol has the potential to generate a range of mind-states/emotions based on absence or presence of alcohol at the time, and the quantity of consumption.
Freedom from addiction to alcohol usually requires group support.
Be clear that you may find yourself facing a variety of moods and views.
Do not play at being Mother Theresa.
Do not expect anything different unless the person is on the road to recovery, and that requires motivation and support from a skilled person/group.
Kindness, clarity and wisdom matter without being naive.
Love
Christopher
