Well this is a tough question to answer, but still I will share my feelings about it - First of all, there are uncountable forms of " love " - For example, love for siblings, love for parents, love for friends, love for elders, love for younger ones, love for your teachers, love for your bae ( girlfriend ) etc - The love you described is of bae - I will agree upon the fact you shared that there could be only one true love, at a time - So with your love ( I mean to say bae ) everything should be open and bold - Even a single thing should not be hidden between both - It should be long-lasting, till death - Care is mandatory - Love is not a fantasy or a toy, but it worth much - Only lucky people find true love..... P.S : That's all between me and my bae
