Not sure whether he's just overprotective 或者 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 首页 even though the taxi had already driven past his house to get to mine - he never does this with any of our other 老友记 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 你 hear stories from magazines and things, they always seem to start out with something similar - am I just being paranoid? lol
