For some strange reason we all hope our alcoholic will get better and our life will improve. And, it probably will improve if they stop drinking.
The reality is we (you, me, and the others around here who live this) can not change these people. They are reluctant to change. And you life will not be any better with this cat in it.
Choose your path. There are two in front of you. One is familiar and comfortable, yet bumpy and full of pot holes. And unfinished. It will never be smooth. But it will be there. The other is unknown. It might be better beyond you wildest dreams. It might only be a bit better. But it is certainly smoother, and it leads to a much calmer place. Promise.
"Two roads diverged in a wood, and I--
I took the one less traveled by,
And that has made all the difference."
And oldie, but a goodie. And I can't help but think old Bob Frost was talking about this exact thing.
