The one?

I've been dating my boyfriend a little over a year and Im so in love....to the point where I could say I want to marry him....were sophomores in highschool so we have a lot to go through, but I love him so much I can't find the right words to explain him except perfect for me....does anyone else feel this way? He also feels the same way for me, and demonstrates it to me everyday, so we're head over heels....now my question is, is this a feeling someone feels when they know they have "the one"?
