Based on the intrinsic complexity of personal feelings, there are an endless number of reasons why relationships fail. However, I believe there are 3 primary factors that form the basis for which every other problem stems. When a relationship turns sour you can be sure that at least 1 of these 3 factors is to blame.
基于每个人感受天生的复杂性,有无数的原因会导致情侣分手。然而,我认为有3条主要的因素是导致其他所有问题的根源。如果一段感情开始变坏,那么可以肯定这3条因素里面至少有一条是罪魁祸首。
