hey peps

I need your help so

basically there's this girl I like but in my mind she's acting weird basically she invited me to hers but nothing sexual happened not even touch ( she somehow resisted me despite what i knew such as showing I know what I want that I'm confident etc can take ages to write) bassically the week before she was really into me and we got sexual even though i couldnt get it hard for sex -.- ( she still cummed from the alternatives though i saw first one come out basically i think she's trying something
at first I just sat down being teasy blah blah blah ( had hands next to her sides and my face was looking at hers) however when I said something about kissing her (was in teasy way) she actually slapped me gently so i thought it might of been shit test but she slapped me again ( I didn't even get that close) so ?.? i noticed whenever i touched her she reacted with like a not wanting the touch even if it was non sexual (said that I said were just friends and that she doesn't touch friends)?.?
i thought that i go take shower i did came back down with just a towel she didnt ask about it or anything but she seemed to avoid looking at my body for like half an hour. we talked sexually kind of like about losing our first time etc even went onto blowjobs etc ( teased her and said its not that good anyway something like that however she replied saying its good blah blah then i go on about a bad time) ? perhaps i should of just said i just think they are?
went to Tesco i think she tried shit testing me by getting me to pack bags got her to instead. came back later in night somehow randomly she was talking about some guy and that she had sex the night before saying guy fit etc ( i tried making it look like i was pretending to be jealous) ( tried making it obvious by saying I'm so jealous blah blah while smiling about it ( she even showed a pic of his dick to me so ?.?)
i thought she was suggesting something tried to escalate with a lil bit of touch but again flinching and threats of slaps lol :L
then later we slept strangely she slept in same room as me even though there is a spare room etc ( talking sexual again ( mentioned she got atext about if she ever tried bj or something (told me before she did that) so i was like well i dont need to ask if you do that (more teasy at time)
next day i woke up she was asleep although talking with me a bit so when i went downstairs she followed me after like 1 minute(wtf?) talked a bit seriously about things included teasing etc some of the serious things made me discover that her feelings are confused about me. at one point i was blunt those questions got a i dont know answer.
later she was playing music strangely like 90% was love songs and a few was very dirty. i felt like she was subconsciously communicating a message ( however i dont know if she ussualy plays love songs so much) she looked at me during the songs to so mmmm even though i tried my own test by paying full attention only on tv (actually used perhipral vision to check if she looked at me during them spy style lol)its like before certain phrases she look at me as if relating it to me ( mostly romantic things but one was very rude going on about swallowing cock so :L )(before the love songs i was not showing affection i think at time i was trying to get her to chase me instead after losing something which was me after her) I think showing the affection on first day was a bit too much didn't know the right amount...
she strangely involved me in things and cooked for me etc... she got me to help her with washing i dried them up ( perhaps that showed easy manipulation but i didnt bow to other silly requests) when i asked for pop near her she did bring it but the phone which was right near her she didnt until i teased her for being lazy. ( i did that taking liberty things where i dont ask i do such as when i was thirsty i got some pop)
i noticed the way she messages me is different than the way she messages others. more detailed unlike messages i got ( although it was bbm I only text through normal texting means) NOTE: was the same before the fling so not sure if its important
she told me things about her being raped etc ( her reason for not liking touch with FRIENDS) ( confusing why we fucked before then) through talk she suggested that she take me to a club one night or something like that. ( when i said a certain song was crap she wants to prove its not by it being played in club)
i noticed she displayed bizarre body language quite a lot of the time she seemed very nervous even when i didnt sit next to her ?.? ( shes mainly like poker face so this was hard to understand her mind and bizarre when she showed signs) unfortunately lots of the psychological things I tried to comfort her did not work she doesn't seem to visualise and feel what is described.
( strangely she also changed her views on children she wants a kid when last week she said she did not.-.-) she changed her leggings in same room as me so -.- I didn't bother looking though.
I think my phone game fucked me up on this one

I think she's trying some sort of game and possibly seeing what material I am?.... I don't want to seem mean but I have the impression that she's not socially intelligent as i assumed she was ( i think sometimes she not even understand teasing and flirting) ( she's had it pretty hard in life so yeah and yes i want to try to get her in the sense of a GF if not i just move on and remain friends)
what's your take on this?
PS any material that will be great to learn from will be appreciated especially in cases like this and texting to. and video examples of these alpha qualities things be great ( not fully sure if my speed tone etc is great or not)
