Well, you can slowly let him find out how old you are. On your birthday, if you have a party then obviously he'll find out that you are 14. From a cake or if your friends punch you. If he really loves you, then he won't leave you for your age because he's dating you while your 14. Not 17. Age doesn't matter. It does if one of the two in a couple is over 18 and the other is under. Good luck.
