Please take some time and heal yourself first. You and your children are the most important people in this equation at the moment. If you still have feelings for your w, then you aren't ready to commit to someone moving in and being around 24/7.
Take the time to get settled into your new single life and above all else, help your children adjust. Bringing someone into the mix, who according to you still needs to grow up a bit, is only going to create a lot of crazy making behavior and it certainly will not be a calm atmosphere for you and your children. There will be just too much drama and if she's not willing to stand by and watch you put your children first...then she's out...period.
Work on you and take care of your children for now.
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.
