Promises

Is it true that promises are there only to break them?
You... YOU promised me to stay with me. You promised not to leave me.  From the first letter ever you wrote you promised not to let anyone into so deep in your heart. Am I still only one there? Or has someone else occupied my place?  You told me you can't live without hearing my voice, without getting messages from me. Why it all changed? Now you better ignore it all than answer or listen :) You told me that I am everythign for you and that's why you don't need others? When I stopped being everything? You told me that you are afraid to lose me. Why you left me? You told me that everything is forgivable. Especially for the one whom you love. Did you stop loving me that you are not able to forgive anymore? You told me that you don't want to leave me because some small fights or some misunderstanding but still it was what you did. Left me for misunderstandings and small fights. Don't you miss me anymore as you wrote in every letter how much you miss me and can't wait to be with me to hold me and love me ? You told you miss time we spent together even those bad times when we were together and now you don't even want to talk to me? What did I do so wrong? You told that you haven't had anyone with who you felt so peaceful and good. You told that you thought is the sign that I am the one to spend rest of your life with? Why you decided that I'm not? You told me that you would be happiest guy  in the world if you could name me your wife or one day mother of your children. You told me you love everything about me. Don't you love it anymore? Why? What I did? You told me you felt like you found the one you want to live together with the rest of your days. Why don't you anymore?You told me that you even prayed for us. That we could have long future. You promised not to leave me. You promised to love me. I miss you so freaking much. I miss you and love you. Still.... So much . So so much.
