PLEASE, help me figure out this scorpio guy

im a pisces, been involve w/ a scorpio guy for quite sometime now and lol he's got my head spinning already WTF! when he's convincing me to be friends w/ him he says he wants to get close to me, he pursued me for almost 3 weeks then i agreed w/ him (though those 3 weeks arent easy coz since day 1 were already fighting lol due to his rudeness, sarcasm, he's mean and merciles when he talks to me he keeps on picking on me and i hate him for that so we'll fight and he says thats because he like me, is he normal? lol and he saw how strong woman i am, then he keeps on saying bye and push me away then i tell him okay go on, have a happy life im be fine w/o u hahaha lol then the next day he's back again like nothing happened and will keep on pursuing me ) until like i said i agreed w/ his friendship.. so were friends now, he's admitted how attracted he is to me and how much he likes me, sometimes he'll be very sweet in words w/ me (i think he's not aware of, i hope he wont notice coz im enjoying it lol). he says we shud do it (sex), i said no, then he will keep on pushing, still i said no. then one time, he says he's given up, he doesnt wanna be friends ianymore, i was saddened i then realized i already liked him like im into him, so i said what can i do to make him changed his mind, so wtf he said we shud try it (sex) were both matured i shudnt guard myself lol its true coz he's 33 and im 28 hahaha so okay we did, but before that he said that he liked me that he can get any girl he wants but he spends his time talking to me, thats he's compromise a lot for me already, so i said sorry its just that im not easy, and if i give it to u u might just hurt me and leave me and u might think im easy so he said "if i will think that way about u, its in a better way" so okay we did it. when we did it he's changed!!!
he started opening up a lil bit about he's life, work, where he goes, (w/c we havent actually talked about coz im hesitant to ask), then also one time i was getting upset, he just stop talking and left and the next day explaining that he left bec he doesnt want us fighting, (w?c i actually appreciate coz i told him that before that he shud be patient w/ me and i dont want us fighting) he even said that even if i hadnt heard from him for a month he wont lose interest in me and im so happy to hear that too. i know he's got some trust issues w/c he admitted to me, then theres this one time i was telling him something ( i actually tell him everything im honest with
