[Bilal]

Well I love this one girl. she's basically like family. my parents and heres are like brothers and sisters. So I've known her all my life. i used to know her just well a girl. well the last 2 yrs i liked her and over the yrs i know am positive i love her. i thought she liked me too maybe. it was a weird thought but i believed it. i talked to her all the time by texting her. so in the summer we went to vacation with each other my mom her mom my sister and her. i was siting next to her. she put her head on my shoulder because i let her on the plane. after a little bit i was just holding her hand it was weird but i knew she was awake because when a flight attendant was giving me water she quickly let go. and on vacation she and me were kind of connecting. when we got back she completely like hated me... and when i text her she doesn't reply . i checked her twitter and she said " this person is trying to text me a lot and i really hate talking to them. " And well that kind of says she hates me.. but i try to get over her for like 2 months but i keep trying to text her. 1/10 times she replies. i really don't know why tho. so do i need to get over her or keep trying i really don't know.... what should i do
