It sounds like you have right of first refusal when it comes to custody of your children when your divorcing spouse will be away. However, that's about it. Her time with the kids is her time with the kids however she wants to spend it.. with or without them. Tough noogies. It doesn't seem fair.. and it isn't.. but it is what it is.
She was probably whacked out by your initial financial settlement and zinged back an equally disturbing reply. But.. that's why God created lawyers who know how to wrangle the financials and make it work. The initial shock is the worst. Step away.. realize it's a bunch of hooey and a button pusher.
It's pretty silly.. let's say in regard to bonuses. They can't be counted because the amount varies. Projecting your 'potential' earnings is playing with a crystal ball that's really a kickball. Once the earnings occur, then she can haul your patookie back to court if she so chooses. I know my former spouse is infuriated that he pays me the equitable (not equal) amount of alimony allowed by the state. It's all percentages.
Her proposal reeks of her greatest fear.. having to pay alimony. Her weakness is your strength.. or at least I've heard that.
And nothing is official until the settlement is signed and finished off by the judge.
