The ladylove can 't be replaced by your wife , cuz she is not as romantic as your ladylove ; the wife can 't be substituted by your ladylove since she is alienative ; the confidant can 't be superseded by your wife and ladylove , for she is the needs for your soul .

妻子不能替代情人，因为她没有情人有情调；情人不能代替妻子，因为她没有妻子的亲情；妻子和情人都代替不了红颜知己，那是心灵的需要。
