A relationship has several stages: a beginning stage of two years, a middle stage of five years, and a long stage of ten years.
When a relationship begins, communication is the important thing that tells you what matters to you, and, as for the other party... what matters is that you know how to communicate and that your nature is ready to communicate, to the extent that you actually find yourself comfortable in the relationship.
If you have difficulty expressing yourself, or you are not keen on dialogue or conversation with the person you are connected to, then you have affected the relationship negatively, because communication in all its forms is important for starting a relationship.
Communication means opening up
Communication means trying to change
Communication means stating your opinion and getting to know theirs
Communication means your desire to share
Communication means your attempt to talk about yourself
Communication means getting to know their opinion
Communication means expressing your feelings
Communication means stirring their feelings toward you
Without communication, you cannot reach any of the psychological matters you need in your life and that they need in theirs.
Having a person with you without communication means that you get none of the psychological needs or feelings you need in your life.
