How should i react my husband didn't acknowledge my birthday but he knew that it was my b day?

It's understandable to feel hurt when your birthday goes unacknowledged, especially by someone close to you. Consider expressing your feelings to your husband calmly and honestly, letting him know how much it meant to you to be recognized on your special day. It’s possible he may have forgotten or thought he had acknowledged it in another way. Open communication can help clarify the situation and strengthen your relationship.
