What awesome news about your day w/ your kids. That is great! It is very refreshing to have them remember all the good times and help validate that you are not crazy.
I'm sorry about the court issues w/ the W. I'm facing a potential showdown myself where W and I are to undergo a "parenting evaluation" to decide the permanent custody situation for our D. This step will require us both to speak to a psychologist and I'll have to express my concerns about my W's depression, emotional stability, and drinking. I'm in the process of gathering that information now and I'm not really pleased about it, to be honest.
However, like you, I'm hoping processes like this will help to sober up my W to the realities of her claims and of life on the other side.
Let's hope your court proceedings go well for you and cause your W to have a welcome to reality moment of clarity. Some mild clarity from her would do a world of good right now.
