I had somehow a good acquaintance (in the sense of communicating well), let’s call her Nastya, who, say so, liked to have an active sex life with different partners.

We met her by chance and talked to her. I find out that she has a permanent boyfriend, they love each other, all business. Well, I say, if so, and I ask in a joke:

Will you not even change him?

And then she gives me an epic phrase, which can safely be entered in the "citations of the great...", khm, pick the word yourself in general)) :

"I will, but since I love him so much, he will never know about it.

After a while they married.
