She said she "maybe" slept with 2 guys. I'm assuming one of these was you. Do you know who the other guy is (maybe she cheated on you before :P )
Anyways, the fact that she would be okay with sleeping with another man means that she is not content with the relationship you have. It's not about whether she did it or not, it's about the fact that she WOULD want to do it.
You cannot stay in this relationship.
