Most of the time the main reason to love is lack of trust if we don’t have trust on our beloved then we cannot get success in love. This is basic reason for love problem. Other reason is entry of third person. Whenever there is entry of third person your love relationship get effected. So don’t be so interested in third person. Next thing is reason to failure to get desired love. May be whom you love He not interested in you or he / she love someone else. That time your desired love ignore or avoid you that hurt you lot.
