No on the alimony part. By going to FL without us, she is effectively giving over primary custody and didn't even realize she did it. And then there is the whole mental side of things - hell, I even have a text from her saying that if she had to go back to FL without them (happened last month - when my son said he didn't want to go if I wasn't going)that she would have ended her life that night.
But yes, I have a nuclear option...
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
