why am i never good enough?

i wish you would tell me what i did wrong? I'm not sure why every boy does this to me. every time i get close to a boy they disappear, why? i can never figure out why i am never good enough or why they feed me lies and then leave? "you're so cute" and "i care about you a lot" then why are you still not talking to me? what did i do wrong. how can you go from having me lay on your chest to the next week not even talking to me? it fills me with so much confusion. they always get me addicted to them and then leave. i am so tired of it. especially this time. i am so attached to you, more than i meant to be. and you seemed like you were attached to me to. i guess i was wrong. all those late nights, all those cuddles, hugs, kisses, laughs. i guess none of it was good enough. maybe one day i will understand why i am not good enough for you.
