How to know what is really going on?

so, there is this guy that i really like, he moved to my school like 6 months ago, and i liked him since then. We had a cl together and we would always stare at each other, i thought it was coincidence but like 1 month ago i added him on facebook and said hi to him because i knew that he wasn't going to do anything. Also he had a girl friend and well, he wasn't going to be flirting with other girls. so we started talking and then txting. and he said he liked me and stared at me but he also thought it was coincidence. so we kkepton txting for like 2 weeks. and then he broke up with his girlfriend :D. then he started to seem more interested. so we hung out at school during lunch. so this one time, he asked what i really wanted to do and he said that he really wanted to kiss me. and we kept on txting after that and yeah it was all good. but now that he was single i had more girls to compete with and then two of my friends like him as well.so we hung out once, and i enjoyed being with him and then we kissed, and we walked around holding hands and made out a couple of times and yeah it was all cute and stuff. so after that i went home and he txted me saying he enjoyed being with me and that he wanted to do it again. so a day after he went to a party and i dont know what happened but that night he txted me sayiwasn't wasnt sure about his feelings and thdidn't didnt want to hurt me and that i should just forget about us as a couple. that crushed my heart and i wanted to punch him in the face. so my 2 bffs knew about it, and a week after that, i went out with my friends and we were talking about it and i got mad and i said that thing about punching him and so they dared me to go to his house and slap him for what he did. so i did, and it was like midnight and i was wearing a tiny dress and high heels (clothes that i dont usually wear) and so i went outside the car, (he was already outside because i txted him) i grabbed him by his shirt, kissed him and then slapped him and then just left without saying a single word. that night he texted like 10 times and i did not reply. so the next day we talked and he said he was sorry and that he wanted me to be his girlfriend. so i said he had to do more than that. so we have been texting bhasn't hasnt asked to hang out or anything. i dont know what to think about this. my "friend" said that maybe he just wanted me at that moment because i sorta looked like a hooker. and that makes me kinda sad. what do you think?
