What would be her response to you telling her you are going to call her Dr. or better yet, if she has an appointment soon tell her that you are going to accompany her to her next appointment to be sure that the Dr. is aware of all the needs to be known.

She probably would feel that is was an invasion of privacy but if you take the other route it would come across more as concern for her than being sneeky and going behind her back. Have you discussed all the things with her that you have posted about here? If so, then you are genuinely concerned and as her husband have every right to make sure she is cared for to the fullest extent. I think what I would do would be to talk to her about these things and then tell her you will be going to the next appointment. Gently tell you that you are forcing the issue because you are concerned about her and wish to talk to her Dr. face to face to make sure all the bases are being covered.

I wouldn't make the lack of sex drive the main issue though. It really could be all the other problems she is having that is causing a problem in that area so stay focused on those things. Good luck!
