Its been a full month and a half since my ex has contacted me, nearly 3 months since I broke up with her. I still think about her and what shes doing every day, about whos shes with, whether shes thinking about me. I have been checking her IG pretty regularly and she hasnt posted anything since the last time we had talked, which seems out of place for her, which is definatly some of the reasons I have been wondering about her. I have been talking to someone else and just feel flat out guilty, i have a strong feeling I will be in a relationship with this girl, especially after the dates we have, but I digress, I feel guilty for moving on. My heart still belongs to my ex even though I know she would never ever change, Is that crazy to feel guilty about moving on after a long term relationship? She did cheat on me after all. And along with the guilt comes the feeling that the same thing will happen in my next relationship, Irronically enough the way things are going with the girl Im talking too now is exactly how things started out with my ex, is it normal to feel this way? and how can I stop from feeling this way? Just all the things with the new girl is reminding me of my ex, almost like a PTSD, I dont want to detract from how serious PTSD can be but it most definatly feels like it considering I still wake up and have panic attacks thinking im in an argument with my ex  or shes off doing somthing behind my back like she was.
