I was surprised that 58% of LDR are successful. For some reason I would have thought it was much lower.

These were some of the challenges listed: (66%) LACK OF PHYSICAL INTIMACY (55%) WORRIED MY PARTNER WOULD MEET SOMEONE ELSE (50%) FEEL LONELY (45%) EXPENSIVE TO VISIT (43%) GROWING APART (40%) LACK OF COMMUNICATION (33%) TIME DIFFERENCE (24%) DIFFERENCE OF OPINION On MODE OF COMMUNICATION

If you've been in a LDR, was it successful (defined as making 8 months). If you haven't been in a LDR, are any of these challenges the reason?
