Reason and logic are not to be associated with love.Love rules without any rules.There isn't always a specific or proper answer as to why you love a person...neither can it always be comprehended as to why a person stops loving a person,he or she loved so dearly.We can try to guess or speculate as much as we want...love can never really be understood...it can only be felt...and truth be told-i'd rather feel love than know the meaning of it.
It's a limited time we have while we are here...so use it to love.The most important thing-if you love yourself then you are capable of not just falling in love but also sustaining it for a fairly long time.
