I really like this Guy he is 21 and I'm 17 Im hi friend since when I was 12 ....everytime when see him or talk to him my heart beats really fast and all I want to do is kiss him and hug him but I can't cuz he doesn't know how I feel yet he never had a girlfriend before and apparently everyone sees him ugly but I don't he said that he likes a girl from his work. But I don't believe much. He is a really nice Guy..very sweet..kind...cute but mostly I like his personility ...I want to tell him how I feel before I leave to south Mexico gonna stay there for like 3 or 2 months depends if my parents have money still.... we are gonna go in about 2 weeks. And I want to tell him before but I'm scare that he's gonna reject me.. I know he's lil to old for me..but hey my mom met my dad when she was 17 and he was 21 they are together 20 years now and forever ......so should I wait.... or tell him? Advice please? Ten points?
