Separate bedrooms

My husband has gotten used to sleeping all by himself in a room over the last 15 years when I was sleeping with kids when they were little. He is very protective about his sleep and won’t let me join in the room. This has been really hard. Opportunities for physical affection are limited with his busy schedule and separate places to sleep. He is immersed in his job and life goals. This situation saddens me and takes my peace and happiness away. Leaving is not a choice in my culture. It is hard to be a monk who is not impacted by this.
