So there's this guy that I really like and we've been friends our whole lives. He's 9 months older than me. 2 years ago I told him I had feelings for him but he didn't really care. So slowly we started to avoid talking to each other. I still really like him and we have started to talk more and more. But do I tell him that I still have these feeling or no? Honestly I have never felt this way about someone. He has always been there for me and has always had my back. I think about him everyday. But when I'm at home I get "teased" for talking to him. I haven't ever told my family that I have these feeling with fear of being "teased" more. Out families are really close. I really want him back in my life for good but I don't know if he wants that to. I just want him to have these same feelings.
