Deciding on whether or not to become involved in a long-distance relationship?

One third of college students will eventually become involved in a long-distance relationship (Cameron and Ross 2007).
When analyzing a sample of 438 undergraduates at a southeastern university on their attitudes and involvement in long-distance relationships, he found that 20 percent were currently involved in a long-distance relationship, and 37 had been previously.
The saying "absence makes the heart grow fonder" seems to be deemed true by those who have not been separated. However, 40 percent of people who have experienced a long term relationship agreed more with the statement "out of sight, out of mind". One responder said, "I got tired of being lonely, and the women around me started looking good."
However, Guldner (2003) explained that long-distance relationships are no more likely to end because of infidelity than those relationships in which partners lived in the same town. Meaning the quality of the relationship and personality of the individuals are much more important factors than distance.
