Pretty common to cycle through emotions so don't worry about that so much. It's part of the process so just feel them, understand where they came from, then move on. I was also pretty bad at the 3 month mark and then again around the 5 month mark. At some points in my journal I would cycle back and forth daily (why Mach1 started calling me Alice ).
Anger is a normal emotion. I feel anger is the emotion that helps us move to the next step on our journey. I know for me the 'big' moves that I made in myself were initially driven by anger. Be careful though, use anger as a shield to not allow yourself to be hurt anymore, DO NOT use anger as a sword and try to attack. Use it to force yourself to GAL so you stop thinking about her, to set healthy boundaries for you, to say I'm really done letting her and this sitch control me and I'm F'n moving on.
