I don't like being alone in the house either and I have never had anyone break in...but someone was spotted underneath my bedroom window one night.

For you - do you have a girlfriend or a parent you can go stay with on the nights your b/f will be away? Or can you go to a hotel room? They are not that expensive. If he can afford to go away on business..he might have a decent job...ask him for the 80 dollars a night to stay somewhere else?
