Love is subjective, so you are very right.Jacco said:What do you think? Am I right? Wrong? Why?
It is whatever you need it to be. If you see it as a extra-long crush, then that is what it will be to you.
In the end, love is intangible, as you said. It will be treated by everyone differently. Two people that see it as life-long and have endless loyalty and devotion towards one another may last until death. Does that make them better or happier than you? No.
Happiness comes from paving your own way. Don't let anyone tell you you have to experience their version of "true love" to be happy.
Give them the one finger salute and be on your merry way...If it's a family member, you may want to just do that in your mind.
