While there are countless number of reasons for break ups but one out of them all stands out. Lack of love is the primary cause of break ups in relationships. Once love is there the couples can withstand any storm trying to destroy the relationship. Inarguably, love is the greatest force of all.
Unfortunately, most people go into relationship without having proper understanding of their love for their partners. They often misconstrued this love with material things, negating the fact that love is immaterial and it should be treated with utmost sensitivity. Often than not, these people claim to be in love with their other half not because their love is genuine but usually what they are to benefit from the relationship. And if their expectations are not met breaking up becomes an option.
Other factors that are cause of break ups are societally related such as religious differences, race, tribe etc.
In conclusion, love will always prevail no matter the circumstances, be it long distance relationship, bickerings, misunderstanding, financial setback etc. So therefore, it's only the practice of true love that can prevent break ups in relationships.
