[smallbedroom600]

im a 16 yr old guy, so theres this girl i like, and ive been textin her for a little over 2 weeks, whenever i txt her she text back, but sometimes not right away, she txt back " heyy, and heyyy!" if that means anything at all, she has texted me first 2 times already. we usually get a pritty good conversation going and they can last a while. but sometimes they dont, and she will just stop txtin in the middle of a conversation, idk y, and i dont think its cuz she doesnt wana talk to me but just because she forgot or somethin cuz like i said she will txt me first sometimes and txts back the next day, i told her she was pritty and she said aawww thank you, so i tried giving her a hint, im hopelessly lost n need help on whats goin on and how to win her, and also i posted on twitter one time " i wish you would txt me" and 5 mins later she did, so she has the idea
