I just found your post and thought I would seek some guidance. I am a physician (small town internist). Have been married 13 years last week--both of us are 39. (find me at MLC with young personal trainer).
I probably like your husband work long hours--feel that you have to in this line of work. About 4 months ago get ILYBNILWU from my wife. She says everything has always been about me and my career. I have always felt I only was working like I did to get my family ahead. She was primary caretaker of our 3 Kids-9, 6, &5. She started a part-time job last fall teaching nursing at local community college. I know we didn't have great marriage, but always thought it would get better when many pressures lifted.
Now she has feelings for this 24yo personal trainer with whom she has worked out for 14 months. He is reason she is happy again. I have read DB and DR. Am wading through her MLC. Some advice from the "other side" might be helpful to me.
