Do you think there is a chance?

okay so, I'm 14 and I have a boyfriend. He has been my boyfriend since 2nd grade (7-8 years old). Everyone says we aren't going to make it to marriage that we are just kids and we don't know what love is. In a way, I know what they are saying and in a way, I believe it but I also don't want us to break up. He's so sweet, he holds the door for me even when I don't need him to, he helps me with pretty much everything, he's very respectful, basically he was just raised right and he knows how to treat people. I know I'm too young for love, but I think I really do love him and I really want us to last. Do you think there is a chance we will make it to then? (also, sorry if this wasted your time...I just needed to get that out there)
