This must be difficult Katheryn. Custody issues are very complex. I hope the courts place him in the hands of a stable and loving guardian. The only way to stop repetitive texting and calls is to not reward them. Figure out what she is after and do not give her that reward. Generally it is the power to upset you or need for attention. Like a toddler, don't reward the bad behavior and it will stop. There will be no reason to text, if it does not get her what she seeks.
