I like someone I haven't yet met?

Okay so if you have nothing nice to say don't say it all. So I'm 13. And I like someone who is 18. I for sure know he is not older since I've talked to him on the phone and I've been talking to him for 2 years now. So over the summer he told me he liked me I also liked him but I didn't tell him and he is so sweet and all he honestly cares about me. He calls me Hun and sweetheart once in a while he will ask me is there anything that I say or do that bothers you? He has helped me since I used to self harm. He would text me a lot but not as much since he is in school and stuff but when he can text me he will tell me something like this "Hey Hun hope all is well. I miss you." And he will respect me so much. I know you guys would say pedo or whatever but honestly he isn't like that he asks me if I'm okay and not too long ago maybe like 1 month ago he told me he liked me and he would wait till I'm the correct age. Yes I'm aware it's illegal and *** but when he told me he liked me I didn't tell him I liked him back. And I can't stop thinking about him I miss him so much he hasn't texted since he lost his iPhone and he texts me on his iPod and he doesn't have Wi-Fi so yea yesterday he texted me since he went to his friends and said he missed me like crazy and hoped I was ok. So is it wrong I have feelings for him? And how do I tell him I like him? What's your opinion on this? What would you do?
