I was cheated on, what do I do now?

findin out your getting cheated on stings you real bad, when I first found out, it really felt like my heart stoppped I wanted to be sick instead I took it out on the plates and dishes around me yes, I sent them flying, I actually found out from my partners mate, he thought I knew and he told me thats when it hurt so I called my partner asked him if it was true he laughed tried to get out of it and thats what hurts too them fckin lyin to your face. so anyways he told me he loved me I accepted that it was one mistake went back to bein his lovein girlfriend that also went to work made his dinner, done his washing, then a year passes and he fails to also tell me that he has booked a holiday with one of his mates to THAILAND!!! what the f*ck I cried and cried he didnt tell me again one of his mates accidently did thinkin that he had told me, so anyways off he goes leavin me unknown to where I stand away for 10 days, I worked and worked to get my mind off what he was doin over there 2 guys going 2 thailand and not doin nothin RUBBISH… he gets bk and gives me a kiss tells me he bought me some stuff and gives me then goes out to the nightclubs that nite with his mates again where did I stand. I asked him straigh out if he done anyhting when he was away NO is what he said I wanted to believe him but summin was tellin me different. he accidentally left his msn on one night, and I clicked on it there it was, a thai womans name I clicked it and pretended I was him, haha I knew I shouldnt have but fck it, I found out some rather heavy info I didnt want to know, but I left it I said to him one nite I know what you did in thailand and im not bothered hay, I was hurt I just wanted him to think that I werent so I could hear from him. turns out yes he did have sex with a prostitute but I thought to myself I think im an attractive girl, do everything for him why the hell does he need to pay for it he has really lowered his self esteem, but years pass and I never ever in my life since I been with him not done nothin a lot of people have told me I shuld but I just cant do it stupid probably I dunno, but as the story ends, stupid me im still with him, and he still sumtimes stills orders me about do this do that, been with him 5 and a half years I probably shouldnt be complaining but fck me it hurts…
