What is the ruling of Islamic law regarding a husband separating from his wife in bed due to her snoring and talking during sleep, which prevents him from sleeping and affects his work?

It is part of conjugal kindness for the spouses to sleep in one bed. There is no harm for the husband to separate from his wife when she snores, to prevent harm. There is no sin upon the wife because snoring is involuntary and thus absolves her of responsibility, but it is commendable for her to seek treatment for snoring.
