Could use some insight...long...

[Startingover2]

Sounds like you are getting to the restless point. Either do something or move on. You have been at this a long time. It goes back to give yourself a date and see how things are then. It may be tomorrow, may be in 6 months. How long do you want to go on like this? Sounds like your W can go on this way for a long time.
In your conversations I don't hear anything from her regarding the M. She isn't hinting at what she would want, it sounds more like she is finding ways to be friendly and have a working relationship for your kids. Just my opinion though.
