Girl that says she have feelings for you but claims that she cant show them when shes around?

ok i've been going with this girl for four months.this is how it started she used to go with a friend of mine but they broke up so one they i told one of my friends that i was intrested in her but i didnt say tell her so one day i was joking around and wrote a letter with a bunch of letters on it some how it ended up with me saying that i wanted her so we were talking for a few days or so and we started going out after a two weeks we were going out she asked me to meet here parents.three days later i met them come to find out her mom used to work with my mom and her mom already knew me so we got along real quick.then from that day on for like a month everyday i went to her house monday thru friday.thne one day we got into this argument and we talked it out later on that day and she told me how she flirted with two of her exes i didnt like it but atleast she was honest.she said she told me because it didnt feel right to here and she did it because she was mad at me but heres the funny part she cheated on my friend behind his back and lost her virginity to to the guy she was cheating with.for the first month we were cool we laghed all the time told jokes and went out a few times.but she started acting funny like ignoring me on purpose and just doping things that a girl wouldnt do to there boyfriends.so i was getting fed up with it so like in the second month i broke up with her.but we got back toghether the same day because she said that shell change.not to mention that i lost my bestfriend because this mess with her.she was cool with my best friend whos a girl and she used to tell her stuff and my friend told me and i messed up by going back and sayin that she told me but that dosent mattter....so for like a week she was cool again and that next week she started doing it again but worse but thru all this time i was still goin to her house alot well come from school and well just sit and watch tv and joke and play not that much stuff ual shell just tease me in ways.anyway oneday we got alittle more ual and she was into it i just used my hand to please her and she told my friend and said that she dont want to have with me for somreason i dont know.so then she said just later on i said ok.then i broke up with her again for the same reason she wasnt giving me the attention i was giving her she never called texed or spoke when we walked ped eachother.the she said sorry again and then after that we was cool again going into the third month then i started acting stupid like ignoring her and saying things that i know would make her mad.and she started acting the same way again but it was getting more serious so i felt that she reallly didnt want me so i made up a lie to here and told her that i herd she was messing around and broke up with her she was furious and when i tried to get back with her she dinied me and we were apart for like a week she said she needed time to here self so i stoped going to her house the after that week we got into another argument constantly and constantly we argue for the same reason then a few weeks later she said she just wanted to talk.i said ok them on weeknds ill ask her to go out with me somewher shell tell me that shes already going somewher with her friend thats a gay girl now we've been going out for three months and not once she went out with her friend.to make things more intresting she went out with a girl for two weeks a year before she met me.but anyway i was getting mad that she was spending so much time with her friend and not me so thars when i asked her why she ignores me she says because she dosent have emotions for me when shes around me but can talk to me all day over the phone then says that she dosent wanna get that close to me because she dosent wanna get hurt so i say do you have feeling for me she says yea alot but yet i ask her do she wana break up she says it dosent matter to her.i know this is long im sorry but i just need to know what to do because i reaaly like this girl
