I also voted other.
I agree, everyone's situations is different.
(I "personally" think that married couples are
"usually" more commited to a relationship
because of that peice of paper.)
I also don't believe in long, drawn out engagements.
I would think that if a couple has been
dating for awhile.
(example a year) : should know
by that time whether or not their partner
is the right one of not.
JMHO
P.S. I did not move in with my husband till after we
were married.
