Hi
I have been with my gf for a year and a month, in all this time she has cheated on me (I found out) at least 3 times as far as I know, but by that time the relationship was a distance relationship which I considereted when I "forgave" her, but now is not a distance relationship anymore and she has never cheated on me again and she loves me etc. etc.
Her sister is basiclly the biggest slut ever, she was married, always cheating, now she has a kid and brings home every night a different guy, so I reckon that she had that "skilL" from her, or at least she used to encouruge her to do what she did to me.
Last night we went to her sister's house to look after his kid while she was out getting pissed as usual, when she came back with her new "bf" and a friend of him, the friend stayed downstairs on the sofa. My gf came down to bring up the laptop in pijama and took her ages to come back (a few minutes), when she did she told me really excited that the guy downstairs grabbed her (she seemed to like it), I didnt say anything, or ask her anything, just all my thoughts about the cheating came back to my mind.
What I mean is that I have the feeling that if at last i hadnt come here with her, she had cheated on me with that guy... at this point I dont trust her at all, and I think this is what gonnaa make the relationship end.
