It sounds like your husband likes pajamas after taking a shower. He apparently feels comfortable with the pajamas but you don’t. I feel that if my husband finds comfort with anything, It calms me down and we are both happy. I let go of rules and regulations because he is sick and I want him to be comfortable as he can be. Sometimes I wear my pajamas all day if weather is bad or I’m just lazy. Maybe you could put on your pajamas to join him and you will feel comfort together.
Prayers for you both.
