I always tell the women, when in doubt if your not having doing the physical act with your husband, do it and see how you feel. Maybe SHE was overthinking it too. Maybe she is just saying what "makes sense" to her, who knows. They will always blame it on something.
Oh, mine did the mirror game too. So if Geronimo once said in the past that he felt she wasn't physically attracted to him, she may say it to him. I don't know why these waywards do the things they do.
Hell, maybe she's telling the truth and thats how she read the "detachment". Bang her now before this blows up in your face, LOL.
