I'm right there with you, even the 3 month timeline. My wife left me in order to pursue her EA and turn it PA. Within a week of leaving she was meeting with a lawyer. I very much know how you feel.
The truth is, there isn't some magic secret that will allow you to not feel the emotions and feelings you're experiencing. This is a very painful thing to go through, and you HAVE TO experience that pain and those emotions. Anything else is just pushing the pain further down the line. You have to USE the pain to grow. Giving everything titles and acronyms (180, GAL, etc) makes it seem like it's a magic formula and you just have to follow the process. I think the truth is that you have to REALLY look inward and be BRUTALLY honest with yourself. Find the thing(s) in YOU that are actually holding you back and work on changing that. The hard work in all of this is making REAL changes to YOU, not just the things that you do.
You don't have to give up hope in order to let her go. I know people say it all the time around here, but even D doesn't have to mean the end. You can't make her come back, but you can certainly make her NOT come back. You can't change her, fix her or save her. If you truly still want to be with her, don't give up hope, but DO give up pursuit and let her go.
