MY SON AND HIS EX-GIRLFRIEND(AS OF 2 WEEKS) ARE IN THE MIDST OF WRITING OUT THEIR FINANCIAL AND VISITATION AGREEMENT.  MY FEAR IS THAT IF SHE FOR ANY REASON GETS MAD AT HIM SHE WILL KEEP OUR GRANDDAUGHTER FROM US. SH HAS STARTED SPYING ON HIM AND ASKING HIM QUESTIONS IN ORDER TO CATCH HIM LYING. ANY SOLUTIONS.
