Dating

I’ve had a crush on a guy since I was 12 and he was 18 at the time. Now that I’m writing this I’m 22 and he’s 28. We both remain single but I scared to ask him out. Other guys ask me out but I don’t go out with them or date them because I know that deep down there a reason I been hooked on a guy for 10 year. I just have a dream that one day we will date and get married and have a family. Sorry if I sound stalkerish I’m not I’ve just imagine my life with him.
