[NATTLEUNG]

so basically i was looking through my friend's facebook friends. and i one of her friends and he was hella cute. so she intro us. We started to talk online and then exchanged numbers. so we texted like almost everyday. Everything was going great, but what i came to realized is that he pretty sexual. like he talks about sex like wayy to much and everything seems to be pretty sexual. For me like i aint ready to do anything like that at alll. So iguess as time goes by, he knows that I wont give him anything, so we just stopped texting. then after a month or so, i text him and iguess he lost or deleted my number because he didnt know who i was when i texted him so i was like okay watever. then last weekend i saw him at a basketball game. and he kept looking at me, like i knew he knew i looked familiar. but ya know i got no guts to go up to him and talk. cause that was the first time i even saw him. but i did text him saying that i saw him and i also told him like who i am so he would remember my number again, but he never texted back. and now i just wonder. i feel stuck. and im hung over him. i dont even know what to do. I want him to want me. Like I know he has been in serious relationships before too. its just complicated. cause after me and my ex broke up, it just feels like i cant open up no more. and he was the first guy after my break up that im willing to let him in. i cant say i like him, but seriously, iono what it is. i miss talking to him and everything. but i dont know anymore. he doesnt even remember my number. ahhh..
