My XW displayed the same sort of behavior. She pretty much checked out for a while and then wanted or realized that the kids were gravitating a bit more to me.
Having lived it...I wonder if you may be walking a little bit on eggshells. If you are, it usually does not work. Be you. Do what you want to do. You do need to always step back.
AJ makes a very good point. A lot of times, the LBS become closer to the kids (kids aint stupid they can see crazy), then when the MLCer decides to reengage, the LBS is left feeling like they again are being discarded.
Always think about the kids. Try and look at things from their perspective. They probably can tell that mom is bachit crazy, but that is still there mom. They are still going to want to spend time with her and do stuff with her. So as AJ says...it isn't a competion. If something like this happens again, then try and go out and do something for JF.
Peace Eric
