I'm sorry you are struggling with this. It sounds to me as though you're still really attached to your ex & having a very difficult time letting go. The two of you are divorced. (I don't recall you mentioning how long ago your divorce became official.) And, based on what you wrote in your previous post, it sounds as though there was blame to go around (as is typically the case I believe.)

From my perspective it appears time for both you & your ex to put your relationship in the rear view mirror, so to speak, & move on with your separate lives. Perhaps this is what your ex is now doing. And so, whether you feel as though you can cope with it or not, the time may well simply have come to accept it & deal with it as best you can. If that feels more distressing than you can tolerate, perhaps this is all something you need to work through with the help of your therapist if you see one. If not, perhaps the time is nigh?
