These relationship dynamics are not what IвЂ™m used to. The big thing that stands out is that you are such a push over. Having an ex move in for 3 weeks is a big deal. You shouldвЂ™ve made a scene and started a fight from day one. Even if I trusted myself 100% to not cheat, I know my wife would not have it. I wouldnвЂ™t even try. You must have a looooong history of being a push over that your husband thought this would fly without consulting you.
