Not sure whether he's just overprotective oder if I should worry

Ok so I have this friend who I think fancies me - although I've never asked but still - and it's only really a little thing but whenever we come back from a night out - he always gets out the taxi at my house and walks Home even though the taxi had already driven past his house to get to mine - he never does this with any of our other Friends and when I've tried to hint that I don't need escorting from the car to my front door he just says he likes walking - I have a boyfriend and he hates him and any other boyfriend I've ever had. I'm only asking because of when Du hear stories from magazines and things, they always seem to start out with something similar - am I just being paranoid? lol
