He only asked how to deal with the distance, not whether or not he thinks they'll work it out.
My college best friend got together with her boyfriend 2 weeks before leaving for college. She is from Washington State, and we went to college in NY. She would go home for breaks, so she would see him max 3 months in the summer, 5 weeks during the winter, 1 week for fall break, and 1 week for Spring break. They were only on the same location for 1 year after college. Currently she is living in San Jose, CA while he is working in Texas. They are still going very strong after close to 8 years of long distance.
They made it work because of a constant stream of communication, phone calls, webcam/skype, and making the best use of their time when they are together.
Distance will be an added stress to a relationship, but it won't necessarily break a good one. With the way most of my peers are, we rarely know what and WHERE our future will be, but that doesn't prevent us from entering into committed relationships. If a part of our life entails living apart, we will face the reality. Some will make it, some won't, I can't comment on that because every relationship is different.
