Westbank....3.5 months isn't a lot of time to grieve the demise of a relationship. Be kind to yourself...heck, you assess that you're already 70% of the way there. That's HUGE!
There will come a time where you won't wait for something to happen on his side of things, and you'll just start taking action on your side.
To help me remind myself WHY it was over, I wrote a long list of the things I couldn't accept and that happened regularly in the relationship. I held onto the list for a long while, re-reading it whenever I felt I wavered.
