Just keep telling yourself that "Home" is not a specific address or building, it's wherever you and your daughter feel secure, loved and can make wonderful future memories w/o the ghosts of the past.
I know you're in a bad place right now but there could be worse things. You could be staying in the house with your ex & remain miserable. Instead you've taught your daughter to pick herself up & never accept emotional crumbs from anyone.
When you're sad, remember when you came from and think about where you're going to.
I feel your pain...I really truly do...I hope that all of the hurt will just eventually go away...because I know how bad it really does hurt...
You know I'm going through the same situation...our house is on the market now...and the divorce papers have been signed...I too, feel I put EVERYTHING into this house and marriage...and to be forced to walk away from it all is truly heartbreaking...but, I guess we just have to remember that we'll be ok and we will get through it somehow, someway...
I can only imagine what you are going through right now. I can relate.. and will be in your shoes pretty soon as well. We only have been in our house about 4 months and even that is going to be hard to break away from. I wish you the best, and know that YOU WILL get through it and be a better person in the end!
