Not really. My grandfather was 11 years older then my grandmother when they got married, its just that she was older and more mature then you when they met. Right now its kinda weird because you just hit puberty and he is basically an adult, but in 10 years when your 24 it would not be weird at all to date someone who is 29, its just weird now because of how young you are.

i'm honestly in a very similar situation.
It seems like a big gap now but come the time you are older it won't be a problem at all. i think if you're mature and grown up about it and your parents and friends agree with it then go for it.
as for cons, not only may the age be a problem but since you guys are in different stages of life that could make it more difficult.
just hope that you two grow with eachother, not out of eachother :)
good luck though, do update i'd love to know how things worked out!
