Love is the base of relation or compromises and give and take system

Sometimes I wonder how easily we use word love without realizing the actual meaning of it it seems everyone running after their dreams and desire and in the process of achieving it either one make compromises in life or or follow the give and take management system and start calling it love and unfortunately we are not responsible for  it because we have grown up seeing all this. though the intensity of compromises and give and take system varies from relation to relation in a husband wife relationship it could be maximum  and in mother and son/daughter  and brother and sister relation it could be lesser .Though there are no predefined rule for this  but I still wonder what is a true love then...........
