How serious was your relationship??

Im just curious, what is everyones longest and most serious conditions in a relationship?? And how old is everyone here?

moi---- first b/f- 1yr, then 11/2 long distance
second- 3 yrs, lived together for 2yrs, engaged
third- 1yr, lived together for 9 mo. just broke up 2 months ago

Those are my longest and most serious. Pretty shitty eh
