This may be true, but it is not always possible. My relationship is the priority in my life. I have other interests, but practically speaking I know that if I were to be unexpectedly alone it would be a terrible adjustment. I would not just move on in a few months. I am good with that. Some people are like that. And it's not just women. Some men also do this. Different personalities have different priorities. There is no blanket rule that always applies.
