all i can say is that.....he shouldn't have to let others judge him just because he is with you, if he really likes/loves you then others should accept it....when i was in school aged 15 i was seeing a 26 year old.....yeah i know i thought i was crazy tooo....but i enjoyed it...and because i was with him i felt older then i was a grew up fast....i started talking more to older people or more mature teens then i would people of my own age.....so again all i can say is he isn't worth it if he lets his friends/other people judge him because he is with someone younger.!
