It’s been over 12mths now and this random guy who I have never spoken to other then basic pleasantries though work (I.e. basic employee/customer conversation) seems to be constantly around? 
It started when he used to walk past me when I was walking my dog, then started walking past my house daily (and almost always shirtless with a balaclava  😬) then he put a note in my letter box asking me to add him on Facebook? Then I got an add from him (I didn’t accept) and then he started trying to message me photos of him shirtless etc. this was over about 6 mths.. then I moved to the other side of town and he msged me again saying “he hasn’t seen me around” (I never replied or acknowledged any of the msgs. He just kept sending them. He’s sent me about 30?) now he found out my new address and keeps going past my new house, he goes past every 5 min for an hour about 2-3 times a day, no idea if he goes past when I’m at work... He’s now progressed to stopping out the front and staring at my house and honking his horn... 

It just seems a bit odd and I don’t know if I’m being paranoid pls help
