Question For The Weekend: How Long Before It's Too Long?

Hiya people, today i'm gonna be asking a question that seem to be bugging a lot of people but they don't seem to get the right answer. So maybe, we can all throw our 50 cents into solving this mystery.

"How long does it take for a Courtship/Relationship/Engagement  to be branded too long?"

For me, an engagement lasting up to a year is too long; a relationship for a year with no word on marriage is too long and a courtship for 3 months is way too long. It's a matter of right or wrong; if you feel it's right, why hesistate? If you feel it's wrong, keep on stepping.
