I am on the other end of your situation. It's still fresh and very painful for me to accept. My 3 year relationship ended 2 months ago. My BF who claimed how much he loved me never left his wife. They have been seperated for a year and a half yet they never filed. It wore me down mentally and emotionally and our relationship stopped working. I could no longer play the role of happy girlfriend knowing nothing was being done to give us a normal life. I spent 3 years consoling him and being the strong partner to make him feel ok while he was dealing with his emotional baggage of ending a 10+ year union with someone he loved as a person but not as a lover. He wanted me there asking me to stay and wait it out, 3 years of this. He has left me now and says he cannot get over the guilt of our affair. All this time I loved him and cared for him, protected him and I feel as if he took advantage of all of it and then just cut me off. All these years I shoved my feelings under the rug to take care of him, I let myself come second, and now I'm alone and left feeling used.

So I know how your ex BF feels. I also know how you feel too. Maybe your ex needs some time and once you spent some time alone, divorced, you can reunite sometime in the future.
