I’m very lucky in the respect that as my values and goals changed, so did his. We basically grew together in the same direction instead of apart. I realize that not all people who meet and marry young are that lucky…hence the high divorce rate.
Like so many have said, I think you are “really” in love at 16 (I am also 16), but will it last? Who knows? Who cares, really? Enjoy being with the person you care about. Worry about breaking up when bad things happen. If you love the relationship you are in, that’s really all that matters, no matter your age. I was in an online relationship with a 24 year old for almost a year – it just ended recently. Did I love him? I never knew him in real life. I didn’t even know what he looked like. But I talked to him for hours every day and we talked about everything. When we had bad days we sometimes fought, and sometimes we comforted each other. We laughed together and we cried together. Was it real love? I think that in some ways it was. The most important thing I learned from that relationship was not to worry about it. Whether our love was “real” or not, it was SOMETHING – and it made us both happy for a long time. What else matters, in the end? When it ended, the thing I regretted most (and still regret) was that we were both too scared of the barriers in our way to fully enjoy our friendship or our love or whatever the hell it was. Enjoy yours.
Just my little ramble for today. 
Yes, Manda JO, I’d do that for him. I’d do a lot of things for him. I have. I’ve held him when he cried, nursed him when he was feeling sick…I have practically carried him when he wasn’t physically able to walk.
I have put up with his horrible jokes, with the fact that some of my friends think he is a nerd and their laughing at me, and I have rearranged my schedule to be with him AND keep good grades at my college.
I’ve done all I can for him. I love him. I only hope that he feels the same.
