Communicate Openly: Express your feelings and concerns to your partner in a calm and non-confrontational manner.
Set Boundaries: Clearly establish your boundaries and communicate them to your partner. Let them know what behavior is acceptable to you and what is not.
Encourage Empathy: Help your partner develop empathy by encouraging them to consider other people's perspectives and feelings.
Focus on Self-Care: Take care of yourself emotionally, mentally, and physically. Prioritize your own well-being and happiness, regardless of your partner's behavior.
Remember that you deserve to be treated with kindness and respect in your relationship.
It's important to remember that changing someone else's behavior is not always possible, and you may need to reassess the relationship if your partner's egoistic tendencies continue to cause distress.
