saying "i love you"

ok well i think too many people throw these words like confetti with no actual feeling behind it.
ive myself am guilty its almost automatic once heard
and ive only ever meant it with one in the sense of i love you and want to be with you i eventually cleared it up with the others alot of sore feelings for which im apoligetic
but ok so i put this out there
i dont get how people can make everyone they are with the one, love them so much, lose thierselves in that person so much(im not guilty of this) every person they are with..in a matter of days hell sometimes hours mins really what has been shared? what is the fountation?
making everyone special..isnt that cheaping the relationship before? falling in love again sure i believe in that maybe but i dont feel that person will ever truly have your heart like the first one did if it were indeed true love i care about many people and date around plenty
and i share and i feel good and some have made me happy and i dont compare and maybe the depth feels similar but never has it duplicated the love i had and still have for a ex of mine...some say this gives anyone after a short stick not a fair shake but to hold true what i said with the one would only go to show the importance of what the one after would get the devotion the willingness to work harder and make this one last i dont know thats how i feel any comments?
