Okay so my friend and his girlfriend have been together for about a year. Theres now a rumor going around that she cheated on him 6 months ago with her ex boyfriend, so he broke up with her. The reason so many people believe the rumor is because she had cheated on her ex boyfriend with 3 guys and he never knew. The thing is we all thought maybe she had learned to that and she seems to really love her current boyfriend, although this was rumored to have happened 6 months ago. I cant tell if her ex is full of sh*t or not though. He admitted that it really did happen, but she denies it. She also said after they broke up they stopped talking, but he said up until a few months ago she kept texting him. He said that when they hooked up he was drunk, and another guy that was with them said he thinks he might have remembered something happening, but he was really drunk. So i cant figure out if her ex is lying about everything, and if he is, what would his motive be in doing so? it all seemed to happen out of nowhere. do you think it is just or rumor or the truth?
