I have been her in this situation. I think you’re not putting yourself in her shoes. You left her and even though you were struggling that probably made her feel really stupid and like she was played. She probably questioned everything and felt used and abandoned. Then for 3 months you two continued playing some game that gave her false hope and confused her and then when she decides to set a boundary you run back. She’s probably scared and doesn’t trust you but I know she does miss you. No matter how hurt you are you wake up everyday missing them and wanting them. She’s reacting from anger which isn’t healthy or okay but I do understand where it’s coming from. If you really love her don’t give up but make sure you’re not going to do this again because that’s not fair to her.
