What's the Name of That Book??? discussion

All I really remember is that there's a teen guy who watches over a girl (I think the used to date), but he's a ghost. And he only visited her at night/ when she was asleep. Also, I'm pretty sure she found a new boyfriend and he was jealous. Hope this helps!

A guess - Shade by Jeri Smith-Ready?

Simone, what year did you read this book?

Is this more fantasy/paranormal than sci fi because of the ghost?

How did the guy die?

Simone, are you still looking for this or did you find it?

No response, moving to Abandoned.
