Dear Amy: My husband … has become so obsessed with his exercise program that he has little time or energy for me. He goes to bed shortly after our children do and wakes up early to work out. … I have talked to him about this. He makes an attempt to be with me, but then goes back to his routine.—Exercise Widow

My fella just puts up with being an exercise widower now, although it’s taken some time for him to accept that this I’m not going to change!
