Starting divorce proceedings

I was away from DS for a while cause reading about so much pain and hurt was making me sad.  My H has been deployed for 6 months now and even though things were looking up and heading in the right direction they stalled again and this time it was me the one that got tired of trying, of giving and not getting nothing in return, I got tired of this empty trade.  I see all this happy couples, how the husbands treat their wives and it made me realized that I want so much more, that I deserved so much better.  Talked to my H and he says he cant offer me what I want, that is not in him anymore.  He wanted to stay married for the kids but I can't keep sacrificing my happiness and getting hurt along the way.  I finally reaized that I wanted him in my life but I dont need him in my life.  It is the hardest thing I've ever done but I told my H that I was ready to let him go and move on with my life, to start a new chapter in my life, to have hope that someday I can rebuilt my life.  I am hurt, my heart is broken but not my spirit, I want to live my life, be happy, I dont want to cry anymore, I want peace of mind, I want to free my heart of this heavy chains around it.  Before it was a possibility now it is a reality, going to see the divorce lawyer tomorrow.  Just hoping to keep it strong through this whole ordeal.
