Your partner must be aware of what you think and what you feel, because only then will you be able to understand and complement each other.
If you or your partner are very closed and never open to express your emotions, feelings, wishes or desires, you must face reality and make your partner see that you both have a problem. Put aside the shame, lean on both of you and carry out communication exercises that allow you to create that affective nucleus necessary for everything to flow.
Everything is shared with the person you love, so in order to talk about your feelings it is important to create an intimate environment that allows you to feel loved and accepted with your virtues, defects and emotional deficiencies. It is important that this space is shared and true, because only then can you respect and love each other reciprocally.
