How does this "EGO" affects sometimes in love?

EGO.......can end up a relation in a flick........ it is the biggest enemy of a relation n the reason for maximum quarrel between any two persons...... due to ego one will never accept his or her mistake n this will result in a quarrel....... n thus may also lead to end of relation....... so one must try n not to be an egoistic......

Ego is another name to the adamency as per my understanding. Things always go wrong when you pay your attention to your own way of thinking without considering others side at all. It's because of once mind set up which always thinks to be correct and does not try to listen the next person. In love also you must always estimate yourself properly otherwise the friend to whom you love would get upset and sad, there by a begining of hatred starts.An ego always puts you to disaster, so one should not have any ego.
