Where will go? What can I do or should I not do anything? ><

i dunno wut to do right now.... basically she left her bf of almost one year for me...we were friends before that since january...in august things got serious and we got closer, we knew each other pretty well...u know how itz normally opposites attract?...well this time it wuz totally different...we had a good understanding of one another...finishing sentences, thoughts, same interests, favorite things..u name it... problems started when i asked her to cut off her ex when i saw him as a problem when i felt a gut feeling somethin wrong wuz goin on...she wouldnt do it... she said she only texted him once in a while... when we argued...i would bite my tongue....she would raise her voice...and for her it would be ok to yell...but then she'd stop when i asked her to... I only yelled at her twice...and when i did it wuz of importance of wut she did not want to hear...which wuz about her ex....freaked out both times i yelled cuz shes used to me being quiet all the time...such a double standard...she cried both times i yelled... n the last one wuz at bout 2 weeks ago...made a scene started crying in the middle of everyone outside at an event we went to... just cuz i asked her wut she wuz gonna do at an event we were goin to on halloween...cuz her ex wuz goin and she wanted to see him...i said if she did...i wuz done...gave her an ultimatum which shouldnt have been that difficult to answer....asked her 7 times before that, she would get pissed off and never give me an answer and it wuz never the time to talk...i even asked her that if my ex went to the event would she want me to see her and she said no...so i dont really see the problem with her making the sacrifice for me...the past is the past..it stays where it belongs..im the present... knotts halloween haunt came...her best guy friend wuz hella chill with me since i helped him with his girlfriend drama n when i asked him stuff told me that the dude broke up with her yet till this day she says the breakup wuz mutual...he also said that she hasnt stopped talkin to him n that at the halloween event we were goin to wanted to talk to him to see if they could get back together....this hella saddened me... she asked me never to fuck her over...to be loyal, i told her id always be truthful....she said she'd do the same n wut....she lied to me....i left their group with my friend at knotts...she tried textin me to explain but i felt she wuz tryin to cover up...the dude never had a reason to lie to me..sat she didnt text or call  sunday same shit...got off work at 930 called her....took 4 damn calls for her to pick up... she still tried blamin all the drama and bullshit on me...but since i can recall and she even knows it...i told her i wuz one of the realest dudes out there...she said i disrespected her and that her friends didnt like the way i treated her...i only yelled twice... and im really good to her n she knows it,, im normally a calm person but she didnt wanna hear any of it which is why i raised my voice...to be heard...out of all the shit i did for her n her friends, even my friends know im a good respectful guy... she tried putting the stupid lil arguments in front...arguments are one thing but going behind my back when i trusted her to still be talkin to her ex is another thing and all she would say is she had a difficult time with the break up which is why she would still talk to him as a friend....bullshit...we spent 2 hours on the phone...she cried the whole time...things got serious...yea i did cry for a bit...she said she does have feelings for me and that their still there and that she does love me... but her heart belonged to the other dude she supposedly left for me?... how does that work when itz mutual? and how does that work when she left him for me?...that shit tore me up....i told her i cut all ties with my relationships so i can build my wall faster....n she cried even more saying she wants me in her life...to be there for her...for wut? to be on the side...n suffer by just watchin her be happy with the other dude...to know that shes gonna be givin those feelings she wuz giving me to him now...to know that hes the one tappin that now? i dont wanna live with that...super selfish when all i did wuz give...even to this day her friend owes me money n she hates me after wut happened at at the event 2 weeks ago...all i did wuz ask her a question which she coulda easily responded with a yes or no n she made a scene...there wusnt really much closure from the talk....i had made a promise to her a while back that we'd stay close no matter wut...but after being lied to..being betrayed...wut to do?....she knows i keep to my word...every time.. i keep my promises...but is there an exception for some?....told her i would only try because of that promise...i felt like shit....betrayed..somewhat broken...monday the day right after....she couldnt even give it some time...tried getting back with her ex...said she talked to him when she called me this past tuesday....to this day i dunno if thats all that happened...she tried getting back with him and he said he didnt want a relationship with her...i guess karma bit her in the ass...she told me i wuz right about everything and that her ex is a jerk...i dunno wut she meant about being right about...told me that after this she didnt want a relationship anytime soon but wanted me to be there as a friend...itz hard...she threw away someone who had her as a priority for someone who only had her as an option...since tuesday didnt call or text her till she texted me on saturday: hope u have fun at Monster massive :)... i said thanks...she texted me later on that night at monster but texting wuz a fail...received them till i left and she had asked me where i wuz at...told her i had been outside the whole time...she said she had been too..said she went looking for me where i said i would be but couldnt find me n apologized for it.. i asked why she apologized she said she didnt know she wuz just feelin weird....she got home said gnite to me...i said gnite...from this i wuz thinkin maybe she startin to realize she fucked up...she cant be that dumb n blind...cuz i know shes not...just hard headed as hell and wants things her way...her ex let her do that...i didnt im not Burger King she cant have it her way...and that would upset her.... sunday no texting at all... today came which is monday...n even tho i know she fucked me over..i still care...from all the gurls that ive been with, theres something different...like a vibe to her that till this day i still cant explain...started up a convo by sendin her a couple names of some tracks she might like...looked like she wuz in a ok mood n we texted for a lil bit...sent her a text around 630... n now itz like 1:43AM n she never replied....she wuz kickin it with her friends...maybe they had somethin to do with it.. i dunno...kinda fucked up that shes askin me to try n be there for her when she doesnt even put the effort for that...even tho shes the one whos the fuck up... the one thing i hate which has happened to me in a few occasions is these gurls really dont realize wut they had till itz gone...im wishing she wouldnt be one of them but now at this point..i dont know where things have gone or wut to do...i really care for her and i dont want to throw wut we had away... from textin and talking from sun up to sun down everyday if we werent spendin time together...shes actin a fool... n i dont know wut to do to turn the script...any good advice will help
