how to break our cycle???

Problem/Goal: i can’t let go, i want a break up

context: its my first time being in a relationship, at first it was all in all happy relationship. until i opened up my problems with her na ayoko na ganito sya, sana baguhin nya yung trait na ganyan. she agreed naman tapos syempre ako, kahit sino, maniniwala at tatanggapin naman yun. until it became a cycle na i would speak up to her the problem and she will accept it but there are no improvements at all. and all along, sinabi nya na rin na i have to give more patience with her, it’s not that easy daw pero she’s really trying. syempre naawa rin ako, ok i gave her chace again. 

ayun na nga ang naging cycle, puro sya salita. napagod na ako hanggang sa i asked for a break up. hindi sya pumayag. she begged. she knows where i can find, kaya nya gumawa ng paraan para makausap ako at makipag balikan. she really knows what to do kapag break up na. 

it’s been 2 years since we were like this. several times asked na mag break na lang kami. im tired, she’s knows im tired, pagod na rin daw sya pero she can’t let me go. first namin ang isa’t isa, of course every decision i make is not easy, every break up namin, i would break down as well. im at my lowest. it’s not easy kaya alam nya talaga kung pano ako kunin. nadadala nya ako sa emotions ko. i know im also at fault for being marupok. but arggggghhhhhh i want a break up already. nakakapagod. nakakadrain. ubos na ubos na ako. help me, please. how to break this cycle? 

previous attempts: this has been a cycle for 2 years already. tho hindi naman everyday ganito, kapag nagaaway, ganito talaga agad nangyayari.
