Can I Do Something Forbidden For Shalom Bayit?

What is the halakhic weight of shalom bayit and to what extent is it permissible to do something forbidden for the sake of preserving one’s marriage? For example, I have sleep apnea and use a CPAP machine during the week, mostly because it prevents me from snoring and disturbing my spouse’s sleep. My spouse wants me to use it on Shabbat too, since we have young children and sleep is a precious commodity in our home. Should I acquiesce and use the CPAP machine on Shabbat for the sake of shalom bayit?Have a question you'd like answered on Responsa Radio?
