EDUCATED women are sensible women with their heads firmly planted on the shoulders.
They understand (read have the knack of) how to get things done. They don't need to TRAIN men.
If there are two individuals involved, why should one TRAIN the other.
There's another thing about education. It makes one seek the company of another with the same intellectual level. Then things like TRAINING the significant other do not crop up.
If you're at pain with your relationship, I'm truly sorry for you.
