All of the above, some of the above and none of the above.
I am probably the exception
Most of the boomers I grew up with have stayed in very stable relationships (one marriage)
Most own their own homes in Socal outright and they are planning to age in place, but that is most likely very unusual.
I know some exceptions to the above though (maybe 10% or so of the boomers I know) who are not doing so well.
