LDRs for me are the same as short distance ones, only that LDRs tends to need more commitment to work the relationship out..both types of relationship need lots of effort to become successful in it..and if one slips out any of the basics (i.e. trust, understanding, faithfulness, etc.), it has a big possibility the relationship won't work..of course don't forget that relationships need to have fun too..you can say that all the right attitude are put in the relationship, but if one/both of them isn't happy of the situation or is not having fun, it will just end eventually..
