Does anyone find this creepy or wrong-- why?

My friend introduced me to his cousin who had said I was cute. He suggested him as my friend on Facebook. We started talking on there for a long time so I gave him my phone number. We starting talking on the phone on a regular basis and we really started to like each other. He lived in another stated about 7 hours from where I live. He came up here to go on a date with me for real. We went out and had a great time. We officiated a relationship after not too much longer after meeting each other in person. We kept it long distance until one day he randomly left his home and moved up here just to be closer to me. He's 24; I'm 17. Is our relationship creepy or wrong-- why or why not?
