I want to leave my abusive wife, but I worry that no one will believe my reasoning

DEAR: I recently retired and it made me realize that I needed to make a decision about my abusive marriage.
I am 68 years old and my wife is 66 years old. For years, she limited my contact with my family and friends.

I allow this for a quiet life, or else she will make things too difficult.
We have an adult son and daughter and I have a good relationship with both.
She would be fine for days, but then something happened that made her angry and cursed, and scared me.

All issues receive a personal response, usually within 24 hours on weekdays.
However, all her friends and family thought I was the problem when she complained about how disorganized I was.
I had a miserable life with her but I was worried no one would believe that I had a good reason to leave.
DEIDRE SAYS: You don’t have to prove you have a good reason to anyone else.
You’ve been miserable for too long and need to put yourself first.
You should see a counselor to figure out how you want to proceed.
