Cajun and I had an LDR before I finally moved to Minnesota. I was in Chicago area and that is about 7-8 hour drive. We emailed each other...well I should say we sent short stories to each other as that is how we used to write emails, lots and lots of information, talking about everything, etc. We'd talk on the phone once in a while but email always seemed easier.
For getting together we switched off between him driving all the way, my driving all the way, and then us meeting somewhere half way (The Dells was a regular choice) We did this every two-three weekends, that way it wasn't too long before seeing each other.
It will take communication (duh) and scheduling, especially as there are more people involved than just the two of you, but it is possible and done all the time. The hardest part is not giving up.
Life is about the journey and not the destination,
so what better way to know life
than to wander all the roads and paths set before you.
