Is it normal to start a relationship off what you read?

I met someone over the internet and we talk everyday for at least 5 hours or even the whole day for the past 6 months and theres an obvious connection between us.
Im 18 and hes 23, i live in canada and he lives in the states.

Heres how it started: We were both on skype and we got put into this group chat with other people from the website we played on and we didnt talk much there at first but i sent him a message telling him i liked his shirt he had on in his picture, after that we just hit it off and began talking to each other more and more each day.

Its gotten to point were we know each others life stories and care very deeply for each other. He tells me that no one has ever treated him with as much love or kindness as i have, not even his own family. i just want to be there for him more than ever because hes always been there for me and helped me whenever ive had an emotional breakdown or im feeling blue. i just want to give back to him what hes given me.

We'll watch videos online and be on the phone at the same time; he calls it a movie date until he can actually take me out on a real one.

We never run out of things to talk about and talking to him feels so natural and easy. Its like ive known him my whole life.

He never sends me anything dirty , asks for naughty pictures of me or make me do anything i dont want to do; hes a total gentleman. He tells me that he loves me and calls me his best friend. i know hes not lying about his life or toying with my feelings, he actually cares about me and were always trying to make each other happy. He talks about us getting married and having kids in the future.

We've both been through a lot of the same things (family troubles, parents splitting etc).
its nice to finally talk to someone who knows what youve been through.

I play on this other website and 2 people from there have a simular story to mine, after a year of talking and meeting each other in person they got married and have been happily married for 3 years now.

I just want to know if what i have with this is guy will turn out to be what they had and if it does will it be a normal relationship?

Ive had boyfriends through the years and 1 that turned long distance, which would be like what i might have with this guy unless we move in together. The love i have for him feels more real and different than what i felt for any of my past boyfriends.

I dont want to jump into an online relationship right now because i dont want it to just be messaging each other dirty messages or have phone sex (Im not like that) or have us break up and not have each other anymore. i like just being cute with him, but id get more serious with him once we met.

-is it normal to start a relationship based off of what you just read?
& what do you think about it?

-Im not lonely/desparate, tied down to the computer all day or have no social life. I just talk with him when i can and i want to be there for him when he needs me.
