How to get a girl easy?

Being pathetic won't help at all. You can't "make" anyone fall in love with you--and maybe that's your problem. COMMUNICATE--GIVE SPACE--COMMUNICATE AGAIN. If you like her this much and care for her--then respect her enough to tell her how you feel....allow her to decide what she wants. You feel the way you feel NOW. It's natural. But--you can't force her to come back. You can only tell her how you feel and leave it up to her.
