How do I tell him I dont feel like talking?

I’m talking to this guy and I like him a lot but sometimes I just don’t want to talk and idk how to tell him that without sounding like a bitch or without making it seem like I’m ghosting him. Naturally I’m not someone who needs to talk with someone everyday or multiple times a day and I definitely enjoy his company but too much conversation exhausts me. How should I go about this?
