Oh dear, Bubblegum5499- you really are a pot-full of teenage emotion!
You're 13 and he's 14- life will go on, even if you have to split up!! Shock, horror- that's what happens! A really long time in a 13 year old's world is till the end of next week, so enjoy the relationship for a really long time and then what happens, happens.
Enjoy your time together and cherish the moments of a young, sweet, lovely teenage crush and stop fretting about the future of it and whether you will be going to the same high school together. Because sweetheart, that's what it is at that age- it's a teenage crush and your heart will beat and you will love again, even after it ends.
You have no situation to approach- you just need to enjoy your time with your boyfriend and ensure you have some beautiful, sweet and innocent memories to look back on when you're arguing with your husband in 20 years time.
