Feelings are valid, and it's natural for you to feel upset or angry in this situation. Marriage involves communication and shared decision-making, especially when it comes to significant financial decisions. The fact that your husband made such a major purchase without discussing it with you beforehand might make you feel disregarded and excluded from the decision-making process.
It's essential to have open and honest communication with your spouse about your feelings and concerns. Try to find a time when both of you can calmly discuss the situation. Let him know how his action made you feel and why you're upset about it. Listen to his perspective as well to understand his reasoning behind the purchase.
It's possible that he didn't intentionally want to upset you and genuinely believed he deserved a treat. However, understanding each other's viewpoints and finding a compromise is crucial in resolving conflicts like this. You might discuss budgeting and financial decisions together to ensure that both of you are on the same page in the future.
Remember, a successful and lasting marriage involves empathy, respect, and mutual understanding. It's okay to feel upset, but try to approach the conversation constructively rather than accusatorily. By sharing your feelings and being open to hearing his, you can work together to find a solution that respects both of your needs and feelings.
