If you have brought up a topic and your spouse does not want to address it or change, then just let it go. Regardless of how right you believe you are, you cannot force anyone to make changes.
If they are not interested in making the change, it behooves you and your marriage to just accept. This acceptance lessens anger and resentment, and it helps your partner feel better about themselves too. When partners can accept each other, they create safety for more closeness and connection.
