I think true love is really a way of behaving rather than a feeling. Love takes time to develop. Love is what is left over (hopefully) after infatuation/chemistry/crush diminshes. You can't really love someone until you know them really well and accept them with all their faults, which of course, take time to discover.

Crushes are a part of the infatuation stage. You can have a crush on someone you don't even know.
