Probably after doing research she discovered the reason her plan went detected is that she couldn't afford thevery best hit man available. So, she is asking for $90K a month. Apparently she has the kid about half the time now which scares me because I don't think someone should be parenting a child if they tried to hire a hit man to kill their ex. It shows some stability issues. She says the money is because her son feels inferior to the other kids at his school because they all take expensive vacations and he can't afford them or have great birthday parties and feels humiliated.
Here is the solution to that problem. Change schools or tell your kid to deal with it and the fact he won't see the kids again in a few years. Every kid has this problem. The reason she wants all that money is because SHE is tired of feeling inferior to the other parents and is using the kid as an excuse.
