What is the difference between these sentences?

   Ricardo:   As to meaning, there is not much difference.  Whether one claims to have

Fallen---In---Love,  or to Be---In--Love,  the meaning is identical.

   As to tense,  one would say;    "I have fallen in love with you"   or   "I am in love with you."--Warm Regards, Bruce
