Steve, You do not leave the house under no circumstances. If you leave, you are giving her the keys to heaven! This is your home too and your children are there and need you to be the stable parent in all of this.
If the situation becomes unbearable, then she should be the one to leave. Do not make her situation any easier for her. She's the one that wants to play in the sandbox and go back in time. She's the one that needs to grow up.
Whatever you do, do not suggest your moving out.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
