I also wanted to ask if anyone else has felt this way. I think one of the reasons I cant let go of my xh is because I have it in my mind that no one else will have me. That he is the only one that can ever love me. I honestly think this and so I fight soooo hard for him. I believe he could do anything to me and I would fight to win him back. I know this is becuase I think he is the only one that can ever love me. If he cant love me than how can someone else? Just being honest.
This is good. Honest is good. THIS is what you need to focus your energy on. You are worthy of someone else's love. Keep working on you.
Down the road, if your ex ever did decide to come back, you wouldn't be ready. Work on this, I'm not a therapist, and this is not a diagnosis, but it sounds an awful lot like Co-dependency.
