Every marriage will have its share of successes and failures. But eventually being patient with each other, loving each other every single day, practicing forgiveness and nurturing your relationship wholeheartedly is what makes a marriage successful.
Respect and love will make your marriage very special and your relationship really strong. I think all the couples should adopt these rules to stay together for the rest of their life. We should know about our limits in a relationship so that we cannot harm our better half or life partner.
According to me the success of marriage is dependent on both members. Bith have to give respect, love, time to other. If you are little or more aggressive, other one should be polite and have more tolerance then you.
