It is absolutely NOT about someone not treating you kindly. I didn't see anything like that in the article...

For me, it's about having a very rich life. I enjoy time alone and having my own space. This makes me a better partner for my beloved. We come to each other with a full presence and out time together is high quality.

Like Vicki said, it's not for everyone. It's a beautiful thing to have freedom and the choice to choose what works for you (without needing to judge what others do)
