I know that selling a house you love does break your heart. You think of all the hopes, dreams and promise that went into it. It is heart wrenching, I'm sorry.
I looked at it this way...While I loved the house it would have been hard to live there again, with or without my H. It held too many memories, great ones sure but also sad ones. I decided to cherish my great memories from there without the daily visual of the saddest memories. I don't know if the makes any sense or helps you at all, but I hope it does.
