To simplify and summarize, what Guzzo found is that the increasing diversity in the types of cohabitation and cohabiters does not explain much about why things are so different from the past when it comes to increased odds that cohabiting couples will break up or not marry.
Rather, on average, "Relative to cohabitations formed between 19, cohabitations formed from 1995–1999, 2000–2004, and 2005 and later were 13%, 49%, and 87%, respectively, more likely to dissolve than remain intact.
I was drawn to what psychotherapist, Ken Page terms as “attractions of deprivation” – when we are drawn to people who embody the worst emotional characteristics of our parents.
Basically, the theory explains that we are attracted to people who can wound us the same way we were wounded in our childhood, as our psyche tries to recreate the past void and save us by changing its ending.
The same is true for the United States, which has signed the United Nations Convention on the Rights of the Child, but has not ratified it.
