1. She is probably very confused herself. She is probably overwhelmed with emotions and doesn't know what she wants, except that she wants to feel good about herself. So don't trust what she says. She could say a thing one day, and then say or do the opposite the next day. Remember this is all about emotions and not reason or logic.
2. She will manipulate you whenever she can to get what she wants (or feels she wants). This is very tricky because you want her and she knows you do. Every time someone on this post points to the fact that you are pursuing her and have not let go, you argue back. But if we feel it, then you can be assured that she feels it to. She will only believe that you can really move on without her when you really believe so yourself.
3. You need to loosen up a little and not expect things to be perfect all the time, especially with the kids. This is sensitive subject and I could be wrong, but I think you need to use your judgment. This is a tough time for everyone because of your M situation but also for your 13 year old due to her age. My point is that you want the family to feel safe around you. You need to be fun, and choose the battles worth fighting for.
Just my 2 cents.
