The main difference is in a trauma bond; you feel like you can't leave even though you really want to. While in a twin flame relationship, you simply want them to stay and will fight for that, but you do let them go when it's time to. You also retain the willpower to leave if things get too abusive. For example, in my supposed dynamic, I always felt like I could, at any point, walk away, and I would be fine. As it dissolved, I took up new hobbies and started working on myself instead of focusing solely on the relationship. Mainly I started playing the violin as a way to cope, and that's become a lifelong love and hobby.
