i'm 14 and like a guy thats 18

Michigan

I'm 14 and I like this guy that is 18, and he likes me too, and i wanted to know how old I have to be to date him?

It is not illegal in the state of Michigan for a 14 year old and an 18 year old to date. However the age of consent is 16, which means there can be no sexual contact until that age.
