Come back and stay.

OKAY. SO THIS IS REALLYYYYYYYYYY LONG. BUT BARE WITH ME PLEASE I NEED HELP. So me and this guy met when i was living with a couple friends, because he hung out with them 24/7 at the time. He started talking to me, being really cool and nice. Always making conversation. He always seemed like he really wanted to talk to me.. One of his friends even said “stop flirting” and he said “i’m not… not yet.” and looked at me and grinned. and one day we were all hanging out and we went to walmart and he’s like “want to go in? i don’t if you don’t” so we went in, he was all chatty and happy and talking to me. we got back in the car and he was like messing around with me like lightely hitting me and messing around and laughing and having a good time. then when we were alone he asked me if i was ok, and told me he was there for me if i ever needed him and stuff. then later he asked for my number, stoked of course, i gave it to him. well, we texted almost everyday for a while. but i didn’t see him again for about a week and when i did he acted all awkward but gave me a hug and stuff when i left. he calls me by my nickname… then we still texted or talked on the phone almost everyday. then one day he told me he didnt want to talk as much, i was pissed but said whatever ok, 2 days later he texted me apoligizing and saying he fell for me and liked me and stuff and wanted to catch a movie, eat some popcorn, and drink some mountain dew and hang out and stuff. i said ok. called me not the next day but the day after and still stuck to his story saying he hoped everything worked out between us, that he still really wanted to hang out, loved me, and wanted me and stuff. we talked for about 2 and a half hours. then later that day something happened, and he had to go away to the hospital for a week, (like he isn’t mental, but he was having some problems, don’t judge, i’ve been to the same place myself) and when he got out he was acting weird. like he called me that night and we talked but when i asked him about the date and stuff he acted like he never said that, he said he didn’t like me as anything more than a friend, i wasn’t his type, and he didn’t want to date me or whatever. heartbroken, i hung up on him. next day, he goes over to my cousins house, and my cousins husband punched him because of me.. he called me all mad. a bunch of stuff went down, i ended up having to go to the hospital for a couple days. when i got out, we texted and called a lot, like it was back to normal. then one day he called me and was like “call one of your friends to come meet me i need sex so bad” i was so heartbroken, but i pretended like i didn’t like him, and i didn’t say anything i just said no i’m not doing that. then he said “well, where are you?” i said “at home” he said “i don’t live far from your school, you should come live with me” then it was silent for a second and he said “****, i shouldn’t say that, anyway..” and changed the subject. like WTF? topsy turvey. then we got off the phone didn’t talk for a week and a half after that, A WEEK AND A HALF. we didn’t go that long since we met. we have always talked everyday unless there was a reason we couldnt like no phone or something. then i like made him talk to me and he blew me off and was being a jerk, and it pissed me off and made me so sad and heartbroken… then i cussed him out for it and he said “i have my own problems i dont need to help you with yours” and “i don’t like you as anything more than a friend” and wanted me to stop calling him the nickname i had for him ever since the day i met him.. i mean, that’s what i know him by dammit. it pissed me off. and then he was just being rude and a jerk. the next day i cussed him out some more, then we kinda made up a little and talked and stuff. then 3 days later he texted me and we talked for maybe 5 minutes then he said he had to go. and it has been about 5 days and he has ignored me ever since. and he has been flirting with this chick all over facebook, heard he’s been trying to have sex with her too, and idk what to do.. i honestly fell so hard and so fast, he is so biploar and just changes his mind so much, idk what to do… i don’t care if we are never together, i just want us to be best friends like we used to be, talking everyday… idk what to do. please help? this isn’t the whole story, but you get the gist. help me please?!?!?! thanks. and i apoligize for length.
