I suspect a potential stalker?

everyday I go back home from work around 5PM and everyday I see the same guy passing by me and staring

whenever I go to the supermarket I end up seeing him there, he would say hello and walk away

today I was in my house and spotted him staring at my house's window

am I being delusional or is he a stalker?
