The two cases are: once my first love spent a Night with a female friend of his, and I was fine with it because we didn't live together yet (and because of my parents we weren't even sure if we will be able to), the other was that my second love asked me sometimes to go to my parents and stay for a day or two, saying some stories I believed in those days (until he lied to me in such an outrageous way once that I just stopped believing even the most innocent stories, it was way after we broke up), but he later had me go back to him to spend a Night there sometimes, having a girl but not telling her (he said that she was worse than I was - I was quite lazy in those days to care about domestic duties as much as one is supposed to), and I went along for a while because my thing was that it is his decision to cheat on her and if it's not me then it would be someone else, we were still good friends - and, I do think already that whenever he had me go to my parents he was with other girls too, so I do think now that he cheated on me, behind my back - if it is something your love admits right after it has happened and (s)he is totally fuckin sorry and you can really see that (s)he is from the bottom of her/his heart then it's ok, people aren't perfect (and then you would expect the same of course), or if it has been agreed on because then it is your choice too, unless you tell that you have changed your feelings about it - but in any way what you don't openly and heartfully agree about is cheating - so yep, in this case, provenly and supposedly I was cheated on twice, thank God it is the past and they are both the past too! ^^
