the friendzone. ughhhh help please?

[Dee]

So I really like my guy friend but he lives in another state. I met him over Twitter about a mutual interest and he asked for my number. I mean when we first started texting it was great. He would compliment me and he would text back super fast like asaperonie and would text first like goodmorning and that's a sign of interest right? A week later I saw a change. He didn't text first and his response time is suppperr slow. So ive had time to realize aye well **** im in the friendzone. But recently we've talked about "us" and he was like "im sorry I can't give you an answer about that right now. Im sorry from my indecisiveness I feel bad." I mean we've sex talked but if I talk about us he changes the subject. Im kinda hurt but I know im friendzoned. He even said he could quite possibly like me in the future but he's keeping things at a friend level.He even text me and told me about how he almost ******. There is a 3 year age difference im 16 he's 19. So what should I do? I don't wanna be stuck on him. Thanks.
