4 year age Difference...?

Of course this is a touchy subject because it is against the law and so fourth. I know what you are going through and as an older person (in my mid twenties) I want to give you advice someone should have gave me. Don't get trapped in any relationship when you are young. Just have fun through high school and hang out with your friends. Like you said, he is going off the college and he is going to see people and you dont want to waste your youth on liking or spending time with someone who won't be there for you. Just know that you like him, see what happens with time and then go for it wheny youre older. Have fun and laugh with your girlfriends for now.
