What is he playing at?

Theres this bloke he drives past me most days when I'm at the bus stop. He also beeps as well. He did stop and ask for my number but I said I was seeing someone which I'm not. I was shy and plus I was taking back by it. The other week which he knows I ll be at the bus stop he drove past with a girl at the back of his car and today I was walking which he must of seen me. He stopped and parked up and a girl got out and went to a sand which shop which I walked past it. What is he playing at. What are his intentions. X
