Those 11 years aren't lost. They are a part of you that will always be a part of you. As far as the hole in your heart, believe me you will feel better. I always described it as feeling like there was a knife in my heart.
I went to a yoga camp, because I was hurting so bad and didn't know what to do as I went through the divorce. The third day of the camp, which had us doing a lot of meditation, I felt the knife in my heart was gone. I highly recommend learning to meditate. It is powerful.
I still wish for a hug from my X. And every time I have given him a piece of my mind I have realized it just doesn't matter. He and I see things completely differently.
And as someone once told me: "It's like talking to your dog."
