How to get over him...once an for all. You don't, he/it is now a part of who you are. You won't think about him all the time, but something will trigger a memory and your right back there. . . get used to it and move on.
“The reality is that you will grieve forever. You will not ‘get over’ the loss of a loved one; you will learn to live with it. You will heal and you will rebuild yourself around the loss you have suffered. You will be whole again but you will never be the same. Nor should you be the same nor would you want to.” ― Elisabeth Kübler-Ross
