Just for the record, I believe your response does Mr. Sims a grave injustice. He is 100% correct when he writes that your circumstances are unique. And his explanation of the several variables that could lead to your situation is right on target. So, why am I not surprised that you chose to attack rather than offer a complete explanation?
Is Texas a state that follows child support guidelines? If so, I suspect that 50% of your income exceeds those guidelines UNLESS you fall into one of the situations that Mr. Sims mentions. And the fact that your ex can keep you from your child for 10 years certainly PIQUED my interest.
I see that Mr. Sims has graciously offered to help you. Might I suggest that you take him up on this freebie rather than rant! HE sounds like he knows what he is doing. YOU sound like you need all the help you can get.
