What's his deal? What should I do? Guy problems help?

There's this guy at school I like him and he told me he liked me. But now I'm pretty sure he doesn't. We were taking for a while and then we stopped idk why. We hung out the first time we went to a movie and it was my first time ever going with a guy. When I'm nervous I tend to get sweaty hands. He tried holding my hand and he didn't care about my hands and in the end we kissed. Someone how I stared to fall for him ever more. The last time I went over to his house he wanted me to go inside but I was nervous cause his dad was home so we stayed in my car. We started kissing and he had to go. The next day we were gonna go to a movie but it started snowing so we ended up not going and since that day he hasn't been the same with me. During Christmas break he didn't text me at all. When school started again I was happy cause I would get to see him he just ignored me. We had 2 classes together but now we only have 1. Anyways when I walk into 5th hour he's already in there. Before he would look at me and say something. Now he barely even looks at me. There's this girl in that class that sits next to him and sometimes I have a feeling he likes her. My friend has 2nd hour with her and one day she said "ugh I don't wanna go to 5th hour brenten is in there and he just bugs me i don't like him like that". Well when I walked into class Friday he had his whole body turned towards her and 10 minutes after class started they started writing notes to eachother. Which bugged me. 20minutes before class ended I went to my car to get some papers. Well when I walked back in I put my stuff up. I had to have my teacher sign the papers. Well everyone was standing by the door so I went around and as I was walking around he just stared at me. The bell rang and I started walking behind him and that girl was Infront of him. Before he started acting the way he did to me. Is he would walk behind me and try tripping me and we would start walking together. But as this girl was Infront of him he didn't do anything. I was on Facebook Friday morning and I went to look him up. I saw that he deleted me and I got really sad and upset. I don't understand why. Do guys do this? My friends say he was trying to use me. I don't see how he was. We just kissed an he doesn't seem like that type of guy. When I hear him laugh or smile I break down and cry. I sent him this message on Facebook and I told him how I felt and if he didn't want anything to do with me to be honest. All he said was that he wasn't ignoring me and for me to chill out and it'll be one. I asked him it'll be one what and no reply. I never post things on Facebook I may post a picture here and there. I was following him on twitter and I saw that he didn't follow me back after he followed someone else so I unfollowed him. Idk I just don't understand why he unfriended me on Facebook. At school he acts like he doesn't even know me. I can't get over him and all I do is wish for him to talk to me. Please help what should I do?

Sounds like a jerk, if he deletes you off of facebook then he's probably done..so you should move on. sorry. Maybe warn the other girl about him so he wont be able to use her too..

sounds like he broke up with you without having the balls to actually tell you. doesnt even have the guys to give you some sort of explanation. feel free to just cut ties and move on until you find yourself a guy who treats you normal

i would just move on and forget about him

I'll be blunt.
The dudes left you. Ignoring you, deleting you from Facebook, not responding - All obvious signs that he's no longer into you. Don't take it personally, he's just the type of guy who jumps from girl to girl. It's not your fault. He's a dick.
