I think Dark Heart did a really good job of explaining what a relationship is.

I was in your shoes, Just a girl. Dating and keeping a companionship with someone at a young age is hard work. There were times when my boyfriend and I could have grown apart but there was something worth fighting for. We used to text 24/7 and were glued to one anothers face for a while. Now it has calmed and "I love you" means more then it used to. We don't always have interesting stuff to talk about, either...but his presence is enough for me.

Also, do NOT give up higher education to be with him.
**Better education generally means better jobs and better quality of life. It also means you will not have to live under constant financial pressure to pay bills and living expenses. (This is a hypothetical)
