What is the true meaning of love being in love and falling in love?

Nah they are the same, just that the difference between the Words using.

SOME EXTRA INFO:

Infaturation is the part where u like that person because she is pretty, it is not true crush.

A true crush is something you think about everyday, and missing her every second when you are not with her. Or it might be as worse as when you are right beside her, you still miss her.
