Is there a chance we will last?

I'm 14, I've had the same boyfriend since kindergarten (our mothers were really good friends so he came over a lot when we were very little), we have only broken up once and that was in 5th grade because his uncle passed and he needed some time, which I completely understand. We were still friends when we were broken up for those few months, I still hung out with him and everything we used to do just without the holding hands and all that good stuff. Anyway, is there a chance we will last? we have a very strong friendship and he's an amazing boyfriend (I know I'm a just a kid but I really do like him a lot). I know a lot of relationships don't last when you're a kid but I just sort of feel like ours is different...what do you think?
