Simply writing it down is a safe method to let it out. Write a letter to your ex in which you express what you truly want to say. Don't keep anything back because you won't send it. Underneath a lot of anger is frequently a lot of hurt, so if tears come to your eyes while you're doing this, let them. This will help you get everything out on the table instead of holding onto things inside. Next, call or text your ex. Let them know how you feel and ask for a second chance. Most likely they were just as surprised as you are by the outburst but once they see how much it means to you they might just give you another try. Finally, go to court. Get an attorney to represent you during divorce proceedings. This is required in most states unless you can prove that you can't afford one. If you don't have enough money for an attorney then the judge may appoint one for you at government expense. Don't delay any longer! Time is precious and there is no better time than now to work through your issues.
