Cash, Isn't the neighbor too short for your taste?

Seriously, make it clear to the neighbor that you have a girlfriend, and you don't want to hurt her. If the neighbor can't respect that then she probably isn't worth having around.
If you are truly commited to the relationship with your girlfriend, then do what you need to do to protect the relationship.
Good Luck!!!
