I need to know! :(

ok so I've been in love with this guy named Nate for 4 years STRAIGHT! I just cant stand being his friend anymore i feel to strong for him! He knows, I've given him more then 100 hints lol i even told him that I was falling for him! I just don't know what to do because he still likes his ex and I just want to show I love him alot! But lastnight we went skating (not together) and when he saw me he gave me a tap on the shoulder and said hey we talked but then he saw his ex.... and it all went down hill from there! I just need to know what to do! THats why I turned to you I really need help.... if you could give me advice that would be so awesome he's my first love and i dont know if he feels the same way! I need to know! :(
