Hmm...Definately can't last long
I disagree.
I was in a number of LDRs before I met my wife. Funnily enough, ours was a LDR as well. Only hers was in any 'short' distance (read: hour's flight).
My first was 16 timezones away. Yes, Time Zones. Omaha, NE to Melbourne, AU. And that 16 fluctuated, depending on DST (when we are on, they are off, and vice/versa. We didn't meet for 15 months, and we kept things going for 2 years.
Another one I had was to Sydney, which was the same thing. The funny thing about Sydney was that when I was there, I a friend from Melbourne who was in an LDR with someone from St. Louis. 12 months later, I was at their wedding. That was in 1996. They are still married to this day.
Another friend of mine in Arizona had a boyfriend in Brisbane, QLD that I met. They hit it off well enough that he moved up to the US. They are married.
One other friend of mine who is now married to his LDR, was from Cape Town, SA. Her? Reading, PA.
They do work; like all relationships, they take time and patience, but in the case of LDRs, they take a hell of a lot of effort, and knowing that each day apart makes the time spent together that much more meaningful (read: not taken for granted) and worth it. Some people aren't cut out for them, but that doesn't mean that LDRs don't work. They do: my children are proof of that.
