I think the desire to be in love really comes from a deeper desire to be in love with God and to be one with Him. I would suggest that you make that your priority for right now.
: God is the only being that fills the void.
I don't doubt your love for this girl. I was in love once. I learned there's a lot more to relationships than love. I still love the guy I was with, but really, I'm apathetic towards falling in love now, until I meet someone who can reawaken that in me. I believe it's possible to fall in love again; however, one should not confuse "being in love" with "natural attraction to the opposite sex". While the second has something to do with the first, the first is not equitable to the second.
