They certainly do NOT follow the SAME steps.

Step 1, Step 2, Step 3A are the same thing. Redundant.
Step 3B -  i had a friend who punched walls and threw things around. seems to work for him.
And the last one about Time, thats not even a technique. Thats you choosing to be alive and not killing yourself.
And I dont see Anger or Hate. Telling yourself that the other person was a jerk/bia*tch, and believing in it even if it isn't exactly true. If you Hated or got Angry you wouldn't have to go through 'Deciding to get over it', or 'Acceptance'. Those steps/decisions just don't come up.
So many threads are opened by people here ranting about this/that person treating them badly, but because they are wimps, they accept it as their luck, or decide that they don't deserve better. 'Deciding that it is over/Accepting' it wouldn't do any good, because it would be empty, or even worse, place the blame/fault on yourself, thinking that SOMEDAY it would get better. You dont just go out and decide and tell yourself repeatedly 'Ok, its over'. It would be difficult to accept, and very difficult to sustain. People always tell you not to question, or 'dont ask why, just accept the fact that it is over and move on'. Thats bollocks. Thats the very reason you stayed a long time in your past relationship. You need REASONS to make it stick and make it easier to accept the fact that it is over. and hate (and being Angry) is a very powerful reason. It is destructive, might not be pretty, but it works. and thats a different method of getting over him/her.
So again, the techniques are NOT the SAME. Unless you accept that the person is like everyone else who has come before, which of course is not true because people are special (at least thats what you would like to think, correct?). Which would make the steps here redundant.
