I am not worried what she does or says to me. Her attitude does not impact me. I am moving on with my life.
Moving on and being happy.
Well forgive me for being skeptical, but 2 months would be record-shattering short time for true detachment. I don't think it's possible unless you weren't really in love with her to begin with. What is far more likely is that you are trying to convince yourself you're detached, and hey I get that. We all want to rip the band-aid off and get the misery over with. Unfortunately grief recovery doesn't work that way. It's not linear, and it's not something you can just choose to shorten. Just be very careful because if you are ignoring your feelings or burying them deep inside then they will explode out 10 times worse at some unpredictable time in the future. The shortest path to recovery is through the pain, not around it.
