Hi Elephant Girl, sorry to hear you are having such a grim time with your ex. I am friends with all my ex’s. However it was only ever possible once the pain had healed and I had moved on emotionally. I am experimenting with the 30 day no contact rule following a really spectacular and final breakdown of my marriage yesterday. Google it. In my case I am not using it as a tool to get my husband back, but as a period of time for healing emotionally, with the hope that we can be proper friends.
The way you describe your ex it seems to me he is akin to a hot kettle, every time you come into contact you burn yourself… I have also read that love is like a drug, go cold turkey for 30 days you get a clearer perspective.
Hope this helps, I really hope it helps me!
Take care of yourself x
