i think it depends on circumstances.
First, basically if one party is already living alone, then
logistically easier.
It does not really make sense to me, if needs to put in a lot of
effort to live together - then might as well get married. I think
if you dont love a person enough to want to marry him/her, then
what's the point of living together to begin with - unless the
circumstances are such that it is not possible to get married at
that point of time and living together is a prelude - rather than
taken as a trial.
I'm not judging the morality of it. I am judging the 'efficiency'.
If it isn't going to work, it won't work. If your relationship
needs such a 'trial' to prove to you that a marriage is going to
work - then essentially it is a flawed relationship to begin
with.
