how do you move on from a miserable life ?

I have been in an eye opening relationship. But he holds the grudges and imagines me to be his x-wife even after I changed my ways. The relationship broke and we are all in the process of moving on, especially after his marriage to another girl. But he holds grudges and he might have done something at work place as well to take me out. I seeked forgiveness for what its worth and truly meant it. Not because I was losing everything around me, but because I was losing him. I lost him already, long time ago. The cursed, vengeful afterlife of a relationship is what I am stuck with. I can leave town but I have no money. I am looking for something outside, but this time that I am here, its miserable. I don't know how to call it peace and move on and forget everything that happened. Its bothering me constantly. Is there a magic spell ? What did you do when you were in a relationship that felt like marriage and had to break it and move on while people are scarring and picking up what is left of you ?
