Can't hold your hands anymore

Everything changed. We built promises and plans together. But what happened? I thought cooling off will be an answer to a definite problem. But it turns into shut downing everything. You have let someone in your life now and all I can do is to watch you in your window day by day. Accepting the truth that I will not have the chance to hold your harmonious hand anymore. Problem can be only answered by partners not by letting someone enter into your life and forget everything about me.
