BuckRogersX: question is clear I think lol.
my shortest "serious" relationship was 7 months but I wonder if there is anyone who had even shorter.
To be able to answer this question, you should have atleast considered marrying the person once.
My shortest relationship was 2 months (just before last Christmas) and, no, I didn't think it would last. He was a strategist and I can't stand strategic people, so I'm glad it didn't last... there was no hope of that!
In fact, he really was quite an unpleasant person. Ya live and learn, eh?!
