Your divorce was something you did not expect to take so long and result in such pain and stress. Now that time has passed, you do not wish to revisit much about it, especially the deals with your ex.
A mutual friend expressed concern over the fact that your ex filed for bankruptcy. While you do not believe this is your concern, think again. Depending on the debts included in the filing, you may wind up on the hook for some or all debt your former spouse took in the divorce.
