Can you ever get over a toxic love?

I thought I had let you go, until I saw you for the first time in 6 months. I managed to get through lockdown with no messages from you however there’s no escaping you is there? As soon as I saw you all my feelings came back. What the heck! We had been broken up for 2 years. Is it even possible to let go of a toxic love!?! I feel like my healing process got reset. Day one of letting you go....again....
