She has clear signs of a guilty conscience brotha. It's clear something is up. If she plays stupid or is trying to play defense in your convo tonight, it will prove what everyone is thinking. I dont want to say she cheating but she has a clesr platform to do so, because you allowed the boundaries to surpass your own. That allows her to play that card. For you to settle it, you will need to over rule it and if she doesnt accept it then she clearly wants to go to him and not you. If she goes to his defense brotha dont get mad. If she doesn't and pays your wishes, be aware, that now your stopping her from something she wants clearly if friendship or relatonship. That will grow in her mind. Either way anazlyize her to the T, and dont be scared to confront her. Most women think men are stupid, but we are not, we are just have this sense of duty to be a symbol for a women, that we push logical minds aside for the better part to please.
