Read that he's struggling mentally a bit after the Tour de France. Not sure how accurate it is, but if so, he should take as long a break from the limelight and sport as he needs. I can imagine it can be very very difficult to relax and adjust once you that race is over, especially for someone who seems quite introverted.
It's possible. Still likely once he gets back to training. To put that behind.
This probably doesn't say good things about me, but I find their relationship annoying.
Focus on your relationship.
