Boyfriend afraid of losing independence?

We have been dating for 1 year, 4 months. We both have grown children, he has a few grandkids. He says he doesn't want to live with me because he doesn't want to lose his independence. I live at his house on the weekends, cook dinner there during the week. I pretty much just sleep at my apartment Monday through Thursday. Any insight into how to progress this relationship?
