Something said is not always something felt. You learn that the hard way. Time does not always heal old wounds, it opens them so they are gaping and it swallows everything. Processing is still ongoing, in the middle or maybe closer to the beginning. New dissonance arrives and clogs up the line. There is too much in your head at this time. Incapable and unable to properly deal, you are emotionally unavailable and unwilling. You would rather be alone than be here. You don't feel what you should feel. You don't act in the way you feel you should and you have in the past. You feel uncomfortable. So you let me go because you have work to do. And I cannot wait for you to love me in the way I should be.
Sometimes things end unexpectedly even if there were signs you chose not to see. My first relationship has come and gone.
