Should I friend request my high school crush?

i have this huge crush on this guy from high school .The thing is I feel like I'm not good enough for him or he'll look down on me.He went off to college , he's in his last year and I'm scrubbing toilets. We met in my senior year in our ap classes and well I just felt a real connection towards him. I don't want him to think I'm such a loswer or what happened. I don't have any commitments towards anyone.No kids, Nothing.So the question really is , will we have anything in common again?
