I agree with Princess. You don't need to rush this besides it's best that you don't for everyone involved, especially your son.
Why can't you tell your ex exactly what you told us here. The truth....you don't know how you feel about her. That's more than reasonable considering what you've been through. Have you figured out any reason that you feel comfortable with as to why this sudden change in her?
What about OW? Have you figured out where if at all she fits in the picture? If it was casual that's onething, but if she thinks it's more that's a whole other kettle of fish!
