I'm feelin' really down right now, PLEASE help?

damn. that sucks bro i would say to tell her how you feel but you said shes dating your friend? so yea remember bros before hoes lol. but yea honestly you probably took to long to make a move.. ive had this happen to me several times and you end up becoming the girls "best friend" just someone who she can talk to and thats all. or maybe she does like you more than just a friend but its difficult for her because shes dating your friend. and i dont know what you mean by leading you on? like just messing with you or what? and honestly your a senior your about to graduate i would say confront her and tell her how you feel. let her know that you still feel how you felt when you 2 first started talking
