Too tired for a relationship

Elle

Broke up with my boyfriend coz I'm too tired to have sex with him and spend general time with him. Is that crazy. I used see him twice a week but honestly i would rather go to bed early. I think he knew I wasn't 100% in. He suggested leaving it be. I agreed. Am I normal? I'm 38. My son is 3. I'm exhausted all the time. We were together a year.
