TITLE: I don't often ask for help, but im asking for it now
POST: I mainly did this just to get it all off my chest and straighten my head but any help would be nice. 

I'll lay this out as simple as i can

I like girl
Me and girl go out
Girl ends it
Girl goes out with someone else
I still like girl
Girl leaves other guy and we get talking again
Girl and i wanna try again. But...
Other guy can't handle us even talking let alone going out
He's now creeping the girl out by standing outside her house for hours on end every night, leaving cryptic messages and just being freaky
TL;DR: 
me and an ex wanna try again but her last boyfriend is being creepy. How can we help him move on and stop being freaky?
