Not everyone has the same way of expressing love and affection, and some people may not see birthdays or gift-giving as important. However, if your partner made absolutely no effort to acknowledge your birthday, it is understandable that you may feel hurt and disappointed. It is important to communicate your feelings to your partner in a calm and non-accusatory way, and give them a chance to explain why they did not make an effort. It could be that they had a valid reason, or simply forgot about the occasion. Either way, it is important to express your needs and expectations in the relationship and work together to find a compromise that works for both of you. Remember that relationships are a two-way street, and both partners need to make an effort to meet each other's needs and show love and affection.
