Am I wrong for asking for me time?

I feel like the bad guy for asking for time to myself and for a little break. My husband goes mountain biking almost everyday. I stay home and do school and go to work. He doesn’t have a job. But he still makes me feel bad for asking to be left alone or get away for a while. Constantly being with people and our dogs and always having to responsible for everything is overwhelming. I know that responsibility is part of being an adult, but I also need time to not have responsibilities. You get to mountain bike, I should be allowed to relax by myself for an hour.
