Is it normal if i plan to shape my future around one person?

I know it sounds bad but that is what is happening right now. Its going to be a year since I met my ideal guy. He is the guy I've drawn in my head. It started with just friends w benefits but eventually hung out more and caught feelings. We started going out to movies, shopping, eating, hanging out at his apt without sex. It just became a thing...a really confusing thing. You know when they establish something before catching serious feelings? We skipped that part. And now, I am here at probably the most vulnerable stage I will ever put myself through. I don't know what I am to him and with everything he has put me through I still go crawling back to him. I just can't leave him. I don't want anything else. I rather be sad and trying to make it work with him no matter how many times he has put me down than try to be happy with someone else. People know me as a tough person but I guess you eventually meet someone who got you literally falling for them and you will look so weak to them. I know how I look to him and probably others who see us. Like poor little girl. That's not how I want to look like of course and especially to him because he is so on top of things. He is five years older than me; he's going to be 27 and I just turned 22. So he already has his stuff together, he's independent, he's settling down with his new place and new job. I am still in the process especially that I am younger than him. We're at a new stage in our lives. He's moving to a new apt and I am going back where I came from so we're gonna be living 2 hrs away from each other. If things were perfect and I can predict anything, I plan to move back, get my stuff together, do my thing while he does his and know that in the future we'll end up being together officially as a couple and forever. I know there are more "fish in the sea" but I feel like he has raised my standards so much. I'll always compare everyone I meet to him and of they're not better than him then I dont want them. So like I said, I'm pretty much shaping my future based on him. But it is in a good way; getting a good job and just being independent. Is this normal?
