I have a fear that I'm being played for a fool. I have been married for seven years now and know that I should have full trust in my wife, but it is just about to drive me crazy. I have tried my best to avoid asking any questions and broke down and confronted her about my feelings. She said she has never cheated on me and never would. She would sometimes get real angry and said she is so tired of the questions. I have tried but can't help to shake the feeling. She even mentioned seperating for a while but we have talked it out and has denied ever cheating. The thing is she asked me the question "Have I ever cheated on you?" Like I'm suppose to know.
Here is what has led me to this belief. She has had an interest in trying new sexual things as in the car and talking more openly about sex. She has even mentioned recently that she would be open to the possibility of another woman as in a threesome. She has said a few times that I don't love her and I only married her because she got pregnant with our first child who is now seven. She also acts like she could care less if I'm around. She works with a bunch of men and has one close male friend she works with who is also married. I know him and she mentions his name constantly. She would also go into work a half hour early every morning and park beside him. She has said it is just a friendship and she doesn't even find him attractive. Since I have confronted her she has been leaving a little later now and not mentioning his name as much. There have been other things too but I just don't know if I'm reading too much into it. She has also always had terribe mood swings and always been really flirty. She had a terrible sexual past before we met, but that was ten years ago and I looked beyond that. I had post a few months earlier if anyone would like to know what other things led to this belief.
I don't know what to do. I am a level headed person and don't know if I should trust my feelings or I am being some kind of neurotic. I have caught her in lies before but feel she would never actually cheat on me. I feel I will have no way of ever knowing because I feel if anything is happening it's happening around the workplace. I can not afford a PI. Can someone please give me their thoughts?
