This is when a guy or a girl start pursuing his or her personal interests in a relationship. And also when someone start having a double mind about his or her partner based on the person's inability to meet his or her needs, interest/advances from other guys or girls, or based on 'bad' advice from friends. Most relationship die a slow death whenever any of the above reasons rear its ugly head. Especially if the person doesn't have a mind of their own, the love in the relationship is not strong enough, or when the relationship is one sided.
And most times, it's usually girls that goes rogue in most relationships. their needs are usually their top priorities. Many of them find it dificult to compromise or put aside their personal interests for the sake of a relationship. And in some cases, friends or siblings can also make or mar a relationship. These days, they do more of the later, than the former. Some interfere in other people's relationship due to selfish or wicked reasons. Especially if he or she is not in any relationship. While others do theirs with the impression or belief they're doing it in the person's best interest. only to help wreck the person's relationship. And the last one (interest/advances from other persons) usually happen if the person is unbalanced or doesn't know what he or she wants. Cos when you allow the interest or advances from other persons to affect or interfere in your relationship. or make you to start having doubts in your partner, then you're still a kindergarten!
