Yes I am a pessimist & a cynic, but I am trying hard to see other points of view.

I've been friends w/a person for 18yrs. I've watched her get married again & seem to enjoy life. She lost her 2nd husband two yrs ago.
She's 71 yrs old. We were pretty close.

She's had odd behavior for over a yr & ive always thought it was due to the passing of her husband. Several times I keyed myself into her house really thinking she was dead bec she'd disappear for days.
Then I accidentally ran into her daughter who told me she was taking her to a rehab for her drinking problem which she's had & hidden all her life. She's never done rehab before. At first I was shocked! Then things started to click into place.

I feel betrayed.

Then the cynic in me starts to think...71 yrs old & now you think you can quit drinking??
Why?

Now I know some r going to hammer me here w/your answers & that's fine, but I don't really understand why someone would decide to confront this problem at this age. I have cynical answers....but I'm trying to be nice & understand.
Most might say just talk to her & im just not ready for that.
Thanks for any feedback.
