Hi!
When a person fall in love (or have feelings for someone) it is something emotional. The question is: how much does the person need the emotions or the other person. Most of the time it seems to me that "i love you" is more like "i love certain emotions i get from you".
Now I don't know how psychology defines love (i'm a philosopher myself).
If you one day lost the emotions/feelings you had would you still want to be with that person?
I agree that emotions (etymology: moving out) make us do things and that can be good.
Some people say that deep inside our hearts (and brain) we are like little children crying (while not knowing what we long for) and just want to be loved.
What do you as a specialist in psychology have to say about this? Please give me some wisdom!
