Whatever it may be, tell eachother everything that you are grateful for. This is a great way to alleviate the tension between you and your spouse. You may not get your spouse to participate but you can change the dynamic of your relationship by being the person to step up and begin this nightly ritual.
By focusing on what you're grateful for, you are eradicating any negativity that you have as well as lessening the impact of fights in your marriage.
Although you can’t control your partner and their reaction, you have 100% control of how you choose to react and respond in your marriage. This is one of the first step to changing the dynamic in your relationship without resorting to manipulative tactics or reverse psychology like many of the internet's worst relationship advice.
