There is some stat somethere that says 95% of addicts cheat. It's simple really, they need to get high at any cost and cheating is a high
My ex was sober when he cheated (though I am now sure he cheated on me when he was drinking) and NO, it's not about the booze, it's about the personality disorder and the weakness of character.
Everyone woman in my Al Anon had a cheating spouse!
In fact ,most people cheat............went to my gyno to get an std panel done (making sure my ex didn't give me some disease) and she told me she has 3 patients a week who come to her saying their men cheated and need some tests done.
Imagine the women that go to her NOT knowing their spouses cheated
Cheating is an epidemic now!
