You can still start a new life while leaving the door open a crack. You just have to stop trying to look out that door at him, and convince him to walk in and give it a try. It's open, but he has to WANT to walk through it. It has to be HIS idea. You are not reaching your hand out to pull him in. You are too busy creating a new life for yourself. Focus on that. Definitely live your life like your marriage is over.
ROOT~ once again nails it. So sorry to hear you are feeling down. As hard as it gets take care of you baby,,, you need to just for you. God bless and xoxoxox, Ali
