(ex) girlfriend just ended it but still want her and she says later?

[Sean]

ok long story short
been on and off same girl for almost 6 years, she put me threw hell and i still want her, she cheated went threw a partying phase and would lie about it, and treat me like shit, had drunk sex with other guys, and lie about it

we got back and she stopped partying but then she called it off because i accused her of partyying each time she took long ( wrong on my part i know but i had good reasons from the past) and we would fight alot (long distance) but now she called it off, so i of course begged back and got nothing but now she says she'll take me back LATER ON, which im not cool with i think shes saying it cause she likes someone else (she blocked me on ALL social media sites so clearly is hiding something) but each time i text her saying i know shes with someone she EXPLODES and claims shes not,

ALSO i think shes geting back into partying..
i know i deserve hella better, but its been 6 years and i cant just let go, but im the only one whos been true to the feelings WHAT DO I DO
