*Love and Marriage are two different aspects of life*

There may be love but no marriage or there may be marriage but no love 

Lucky are those who are blessed with both

Marriage is not the goal of love nor love ends with marriage to someone else 

Marriage is a lifelong commitment a promise to respect and care for each other and fulfill all the duties, liabilities or responsibilities towards each other and everyone related to both

Love on the other hand is a spiritual attachment with anyone or anything and beyond lust 

In marriage everything is mutual and reciprocal hence so many expectations while true love is altruistic in nature 

In marriage there are so many constraints but love provides you freedom 

Compatibility / kundali , social status, financial status etc etc are  checked before marriage but love happens by itself by the grace of God 

Marriage is usually confined to only one person but love has no number as it may happen not only for one but many  persons even for other creatures, things or events.
