Don't let your PTSD....or your ex.....get in your way of living your life. You have fought through & survived so many other things.....just think of your ex as those things you have conquered in life & don't let him get to you. I know I have serious issues with stbxh......just hearing his voice on a 3 way call sounded like nails on a chalk board. They can bring back horrible thoughts...but then so many other horrible things you have gone through & conquered....you can do the same with this......sorry this is so long after....I didn't see this when you posted it....
Hope you are doing better now.
